[ydl-gen] Slow ibook X11 (2D)

[Stephen Harker]

Hi,

I have accelerated X11 with my iBook G4 (late 2005) and ydl6.1.  In
fact there was a great improvement with ydl6.1 over ydl6 as my
accelerated graphics had glxgears going from around 400fps to around
1200fps (the chip in these later iBook G4's was only partly supported
with the earlier Xorg).  I will attach my manualy edited xorg.conf and
/etc/X11/fs/config that is at least partly relied upon.  Check and
compare with yours.
