There was a patch very recently to the XFree86 CVS tree that looked like
it would fix the DDC failure in the r128 driver.  Try that patch and see
if you get past this problem.

The new Rage 128 Mobility code is on the trunk.  The driver now reads
the display mode parameters from the video BIOS mode tables since those
are the only parameters that are guaranteed to work with the graphics
chip and flat panel in your system (this info is directly from ATI).
I'm not sure how this will affect the PPC code.  If it cannot access the
video BIOS, then I'm not sure if/how it will work.  The M3 code that was
in the tree previously was severly broken, which was why it was never
advertised and only enabled by the "EnableFP" option, so it was removed
in favor of the generic solution that ATI provided.
