Hi All,


I started the driver roulette on the T30, just to see where it could lead.

Some attempts on the T43 show that the radeon drm is not "so" stable and 
often I get a wake-up as a black screen, without radeon, it works fine.

Anyway, on the T30 the DRM console does not enable.
I tried disabling:

uhci
usb
pcmcia
cardbs
iic
isa

iwi
fxp

auich
midi


with this disabled, the system is pretty bare-bones! :)
I disabled most non-essential system buses, which disable loads of 
dependent drivers too.
I don't think I can disable much more and still have a system I can log 
into!

yet.... on sleep it crashes. I was able to catch the error.
I add that even if it says "flushing disk" at the next reboot, the 
filesystem is dirty.

I did not type out all hex addresses, if you want I can try or share the 
screenshot.
Does it give a clue on where it is crashing? maybe another driver to 
test? or something different?
