United States Patent 7,617,530: Rights elevator. Microsoft patent sudo. Or only the gui to have administrator privileges?

This is ridiculous but at the same time so sad. USPTO accepted the request, and now Microsoft have the patent for that is common know as ‘sudo’. Or only for the gui?
Reading from the patent:
TECHNICAL FIELD

This invention relates to elevating a computer user’s rights.
And after:
Rights elevator 114 is capable of elevating a user’s rights; including permitting a task that is prohibited by a current user’s account or the controlled-access application. The rights elevator may enable a user to elevate his rights from that of a limited-rights account, such as a standard user (e.g., non-admin) account, to a higher-rights account, such as an administrator account. The rights elevator may enable the user to elevate his or her rights through user interface 116, such as by presenting a name of a higher-rights account and enabling submission of an authenticator for that account.
Does Microsoft invented this? Really? I don’t think so.
From the webpage of sudo:
Sudo was first conceived and implemented by Bob Coggeshall and Cliff Spencer around 1980 at the Department of Computer Science at SUNY/Buffalo. It ran on a VAX-11/750 running 4.1BSD. An updated version, credited to Phil Betchel, Cliff Spencer, Gretchen Phillips, John LoVerso and Don Gworek, was posted to the net.sources Usenet newsgroup in December of 1985.

Now, i don’t get if this patent is strictly related to the user interface that permit this temporary “privilege escalation” or if they really have the patent for the concept behind sudo, plus a graphic interface.
This patents are getting ridiculous, really.

Install Slackware 13.0 on Acer Aspire One AO751h

If you have tried to install Slackware on this netbook…
aspireonea0751h
…you know that default installer doesn’t see the hard disk, because the kernel needs support for Intel US15W chipset :/.
But there’s a workaround for us, we need to insert in the kernel the module that allows chipset work properly.
You have to download the pata_sch.ko module from here, or take it from an installed slackware, or download kernel-modules-2.6.29.6-i486-2.txz package and extract the module.
This is what i’ve done: i’ve put the module in one usb key, i’ve created a bootable usb key with default usbboot.img image and i’ve booted with the hugesmp.s kernel.
Now it’s time for the little trick, mount the key with the module (or you can setup the nic card and download it straight from the web), copy the module and insert it in the kernel:
mount /dev/sdb1 /mnt
cd
cp /mnt/pata_sch.ko .
umount /mnt
insmod pata_sch.ko

Now you can see the disk, enjoy your Slackware on Aspire One a751 :)

EDIT:
Slackware doesn’t see the hard drive during installation because there isn’t pata_sch module. This happen again when you try to boot your new installation.
So, after installation, when you press the EXIT button, do not reboot but chroot inside your installed Slackware, with chroot /mnt
Then create a custom mkinitrd with the pata_sch module built-in, with
mkinitrd -c -k 2.6.29.6-smp -m ext3:pata_sch -f ext3 -r /dev/sdax
Assuming you’re using ext3 and sdax is the / partition, the module should be present in the installation if you’ve installed kernel-modules-smp-2.6.29.6_smp.
That’s all.
I’ve installed Slackware in an encrypted LVM volume, following the README_CRYPT.TXT guide, except for the mkinitrd command, i’ve used:
mkinitrd -l it -c -k 2.6.29.6-smp -m ext3:pata_sch -f ext3 -r /dev/cryptvg/root -C /dev/sdxx -L
And i’ve used GRUB instead of LILO, because i’ve installed the bootloader in the /boot partition instead MBR, where there is Truecrypt bootloader for Windows encrypted partition.
If someone have other tips about Slackware on this netbook, feel free to write a comment, thanks.
