No graphics accellerator, as far as I know right now, is supported
by A/UX 2.0.  That includes the 8/24 GC.  The problem as it's been
explained to me is that existing accellerator code assumes a
physical==virtual identity for the cards' bitmaps, which is no longer
true under A/UX.

There's no 24-bit support in the Apple X11R4 anyway, just 1-bit and 8-bit.
