acpi resume problems with thinkpad t42

[Thomas Spreng]

Hi,

I haven't suspended/resumed my thinkpad t42 for while (it kinda worked
before when I ran 6.0 stable) and now after updating my system to
6.2-STABLE I can't seem resume anymore.
More precisely, when I try to resume from suspend (S3) the screen is
garbled with horizontal and vertical lines mostly in a black tone. The
system still responds just the screen won't work anymore (switching ttys
doesn't help either).

Anyone has an idea what might cause the problem or can anyone confirm
the suspend/resume works on a t42 running 6.2?

cheers,

tom
