Solution, take 2:
Found the problem. The winner is.. compiz! Well, to be more
specific, desktop effects. All I had to do was turn them off.
I had turned them on right after install, and they appeared to work
fine with the previous kernel (2.6.23.15-137.fc8-i686). However, compiz
would not even start with Fedora's updated kernel
(2.6.24.3-12.fc8-i686). Turning desktop effects off, fixed the
problems with the new kernel and suspend/resume. I use the "intel"
driver and I guess there is some bad interaction between the graphics card
(82852/855GM) and GL(?).
I actually liked the descktop effects, so if anyone has suggestions
on how to get them to work let me know.
Christos.
