Hi there I had a similar problem (may be with another source).

My T42 with PATA drive sometimes hangs on resume from ram. I couldn't
find what the problem is (just had no time yet). May be there are some
problem with X.Org 6.9 radeon driver?
The situation follows:
I had Debian Etch (X.Org, radeon drivers, hibernate package (with
vbetools and radeontools in use), 2.6.15 from Debian) on T42 with
Radeon9600.
If I send him to sleep (suspend-to-ram) and wakes him right after that
it wakes up normally, but if I wake him after some time it fully hangs
(not acceseble via network too).
I seen somewhere on tw.org that it may be because auto-LCD-off feature
may work and recomendation to turn off DMPS before suspend to ram, but
didn't test that yet.

What do you think? Will it help or I miss something else?
