Thanks I saw the branch but didn't manage to actually spot the
difference.

FWIW I ran a patched kernel up on my home machine (radeon) and it didn't
work. Without KMS the X server failed reasonably gracefuly (with some,
presumably spurious, message about the keyboard driver) and with KMS it
switched graphics mode and then hung on a black screen.
I'll keep poking but I'm hampered a bit by my only suitable "test
machine" actually being my home workstation.
I suppose I should poke through 2.6.33..2.6.37-rc and see if anything
jumps out for backporting.

Cool.
Hrm, do I need some equivalent of c) in order to have a chance of this
stuff working?
