It is required for my 9600 Mobility :
- Resuming with the default 607 kernel gives a nasty "melting display"
effect, although blindly rebooting with "Crtl+Alt+F1" then Ctrl+Alt+Del"
works.
- Adding the radeonfb module to the initrd (and video=radeonfb to my
kernel's grub line) gets me the neat fb using full resolution, but same
problem when resuming.
- Rebuilding the kernel rpm with that patch applied and the same settings
as above gets resume working, with this, though :

I'm not sure how nasty that "sleeping function called from invalid context"
error is... everything seems fine after a resume, minus the IrDA it seems,
I'll need to unload more modules and stop the irda service from my suspend
script it seems.
