OK.  The dmesg output looks just fine.  And the SLOTMAN code was
able to set the card to B&W during startup, so that's not the
problem.  (Regardless of pixel size under MacOS, SLOTMAN always
sets the card to B&W during boot;  much more efficient to run 
the console in 1-bit mode.)

So, my guess would be that the fault lies in your X-server.  I
see that you're running Ken Nakata's OSFA server, and I've had
some problems with that one.  Try the server from my web site:

	ftp://ftp.whooppee.com/pub/slotman/ColorX.tgz

This is the server I use on my Mac IIci.
