I have no such problems with a T42.  It will occasionally crash on 
resume, but *very* occasionally, and I suspend/resume at least twice a 
day and often much more frequently.  On the other hand, my daughter 
reports similar problems (on 2.0.2 and 3.0beta) on her R51.  I had 
suspected an APM event handling problem (that would also explain my 
problems when the display is blanked by the BIOS), but maybe it's due 
to the video card.
