If you mean for Xorg to use atyfb, that's technically correct, but I'm
not sure how it's relevant.

The kernel module is only needed for DRI 3D hardware acceleration, for
which the needed Mesa driver isn't available in Debian (or even current
upstream Mesa) anyway.

Except for the part where Riccardo says that the same userspace works
with an older kernel.
Anyway, I looked at Riccardo's original post again and noticed that his
xorg.conf has options disabling all hardware acceleration of
xserver-xorg-video-mach64 anyway. In that case there's no benefit in
using that vs xserver-xorg-video-fbdev.
