HCRX support, first steps

[Michael <macallan1888%gmail.com@localhost>]

Hello,

I just committed the first few bits of HCRX support. This will let you
run X in 8bit colour, unaccelerated. Unlike before, where X wouldn't
run at all.
My next step will be a native driver which supports acceleration, a
cursor sprite and 24bit colour if the card supports it.

Funny thing, I'm using a 24bit HCRX in a C360, which according to HP,
is unsupported. That doesn't stop the STI ROM from doing what it's
supposed to do though. I assume it just means that they dropped HCRX
support before adding the C360.

Either way, these cards are relatively easy to find and probably our
best bet for getting 24bit graphics on hppa - there is not a shred of
documentation or code for any Visualize FX. For HCRX and friends there
is code in xfree86 3.3, which iis what I've been using.

have fun
Michael
