Xbh X server/adding acceleration to XF68_FBDev

[Jeff Rugen]

Well, I've done some more work on the Xbh X server for 16- and 32-bit
support.  I've added some acceleration to the 16- and 32-bit modes, so they
no longer flicker like they did (basically just got the 8-bit stuff
working with the different modes).  32-bit mode seems to work for me (using
fvwm2 and a few applications), but 16-bit mode needs some work.  It's
started though.

This time I put the source with the executable.  Its all at:
ftp://linuxppc.cs.nmt.edu/pub/linuxppc/patches/Xbh-16bit-glibc2x

Now, the reason I included the Framebuffer list is I was interested in
adding acceleration for the clgen framebuffer in the XF68_FBDev server.
What source should I use as a starting point?  (I have the 3.3.3 server-only
source right now).  I'll also use that as an excuse to verify that 32-bit
modes really work with clgenfb.  Thanks.

The patches for Mach64 acceleration in XF68_FBDev are at

Use the Cirrus Logic accel code from the SVGA server, basically the
long term goal is to merge the FBDev and SVGA servers.

More or less: the long term goal is to merge XF{68,86}_FBDev with XFree86, the
single server binary in XFree86 4.0. Unfortunately there's quite some
difference between XF86_SVGA 3.3.3.1 and XFree86 3.9x.
