Sorry, truth is i don't understand why crtc set_base call back
can be call with a null fb, i did just replicate what intel kms
and other part of radeon kms was doing in front of such situation.
It should go down to 2.6.31, useless before as there is no KMS
for radeon in earlier version. The oops will happen when user
switch btw X & vt or in some case when changing mode.

Will clearly state my ignorance in future patch.

Cheers,
Jerome
