I just got the vanilla kernel sources from www.kernel.org. I used the ubunt=
u=20
config from 2.6.22-14-generic, added the iwlwifi stuff and the snd_hda=20
driver, because ubuntu ships these modules separately.

I use the following grub options: acpi_sleep=3Ds3_bios,s3_mode acpi_osi=3D"=
Linux"=20
usbcore autosuspend=3D1=20

The last one is because of powersaving suggested by powertop, but though no=
t=20
working i think.

One important change could be, that i changed the IRQs in Bios from 11 to=20
Auto. I use Bios Version 1.10 (1.11 is out already, but the changelog was n=
ot=20
convincing me to upgrade)

I can send you my kernel configuration, etc.

kernel compilation is rather easy:
sudo apt-get install build-essential kernel-package
#get kernel from www.kernel.org and extract it
#get latest thinkpad-acpi patch from sourceforge site
cd /usr/src/linux-2.6.24
#patch with thinkpad-acpi
#copy ubuntu config
cp /boot/config-2.6.22-14-generic .config
sudo make oldconfig
sudo make menuconfig (add iwlwifi and snd_hda)

sudo make-kpkg clean && sudo make-kpkg --append-to-version "-test1" --initr=
d=20
kernel_image

Don`t forget to place the iwlwifi firmware in the right=20
place /lib/firmware/2.6.24-test1/

after the deb package has been created, just install it with sudo dpkg -i=20
kernel....-test1.deb
