Subject: Patch to cyberfb.c to drive Aurora 64 V+

Hi -

I'm attaching a patch to 2.4.20's drivers/video/cyberfb.c to drive the
S3 Aurora 64 V+ chip

cyberfb.c is a fairly generic S3 driver, so half of this patch is
byte-ordering and probing on the PCI bus as well as the Zorro bus.

Unfortunately, the machine I was developing this on died, and the
patch really isn't finished yet.  It works, but it has some problems
(if you try to start a 16-color X server, you'll see; 256-color works
fine, though, full color had some kind of problem, I recall).  It
also has some "#if 0"s that really should be better conditionals.

But, the machine is dead, and barring a resurrection, I won't be
doing any more work on this code.  It's a good starting point for
anyone try to get an S3 Aurora V+ running with the kernel framebuffer
code, and, I dare say, anyone with another kind of S3 or S3-compatible
card should find it a good start.

Sorry about the half-finished code, but "release early, release often",
so maybe somebody else can get some good from it.

Very cool!

For someone interested in this, there is also my cyberfb and s3fb work:

(also unfinished)
