Ok. I got the OSFA X server, and booted in 256 colors.
As these are my first steps under UNIX, I don't know what are the usual X 
colors.
I get light green and light purple in my windows' title bar.
if  (this is normal,)
     {
    supported_hardware=supported_harware+"Q700 internal video";
     }
else
     {
     here is the log...
     }

/usr/libexec/ld.so: warning: libc.so.12.20: minor version >= 25 expected, 
using it anyway
/dev/grf0: Couldn't get video mode information via ROM driver.
	This is not a fatal error.
	I gather there is no ROM driver support for this screen...
	I will treat this screen as StaticGray or TrueColor.
Screen 0 at 0x423a000, 640 by 480, 8 bpp, rowB 1024, fbbase 0.
rootVisual = 34 ((null))
rootDepth = 8
visuals->class = 0 (StaticGray)
visuals->bitsPerRGBValue = 8
visuals->ColormapEntries = 256
