I tried it on a T30 (2366-085) with 2.6.9-rc1 which already contains
the latest acpi patch from
http://ftp.kernel.org/pub/linux/kernel/people/lenb/acpi/patches/release/2.6.9/
(these patches are very small, am I missing something?).

% echo 3 > /proc/acpi/sleep 

put the machine mostly to sleep
(after stopping mysql, but that is not T30-specific),
but the backlight stayed on and the image on the screen started
to "decay" from the lower right corner.
It awoke fine, but going into X then gave a totally garbled screen.
After a reboot X is working, I didn't yet do further trials with suspend.

The rest (temperature, battery status, ...) works fine as far as I can see.
I didn't yet try ibm-acpi.

Any ideas what went wrong?
