The Rage Mobility P/M is mach64 based.  Only the radeon driver has
xrandr 1.2 support.  The "ati" driver is actually just a wrapper that
loads the appropriate real driver depending on what card is detected:
ati_misc, r128, or radeon.  GATOS only supported TV-out on radeon chip
as well.  for your chip you can try the following options to enable
tv-out, but YMMV.
Option "tv_out" "true"
Option "tv_standard" "NTSC" or "PAL", etc.
