 Possibly related:  I fired up a machine with mach64 video hardware and
 booted a 7.99.25 kernel (which I'd customized to include the old UMS
 mach64drm) and userland.  Like the r128, the X server reported:

 Extra context in case it's relevant.  The main issue is that it failed
 to recover EDID/DDC data from the LCD display attached.  It did manage
 to operate the VGA output, but only at a default 1024x768 resolution
 (spread across a 1440x900 LCD).
