re: xsrc/58133: X server crashes; radeon 5450; modesetting

ati_drv is a meta-driver that loads the right ATI chipset,
rage, radeon, amdgpu, whatever is valid.

you should ignore ati driver things as this is using the
radeon driver really, correctly.  that part is all fine.

i had thought that radeonMapBufferRange() must have been
the right function but if the modesetting driver isn't
getting into that, hmmmm, don't know.
