Your machine is loading the framebuffer kernel driver which will only work
when you configure X.Org to use the "fbdev" driver. You can either set your
display driver to "fbdev" (see further below) or disable the framebuffer driver
on the kernel command line with:
video=atyfb:off
Then it should be possible to use the "mach64" driver *if* the kernel has
support for the hardware. However, looking at the information available in
the X.Org wiki [1], it seems the mach64 DRM module is currently not part of
the Linux kernel, so the fbdev driver might be your only option.
To use the "fbdev" driver, add the following to /etc/X11/xorg.conf.d/00-fbdev.conf:
Section "Device"
Driver "fbdev"
Option "fbdev" "/dev/fb0"
EndSection
After reboot, X should work.
