I finally found the kernel config files for both my 7.1 and 8.0 Mandrake
partitions. Both files have CONFIG_MTRR=y, so MTRR support should be in
the kernel already.

Now it looks like it could be a framebuffer problem. Obviously the video
card has more than zero memory. The config file for 7.1 has no
framebuffer section, while that for 8.0 does, and in that section there
is no line referencing my video card chip, while there are for many
others. That section does have CONFIG_FB_VESA=y, and it also has
CONFIG_FB_VGA16=m, among many others.

The BIOS of this PC is configured to allow QEMM in a DOS boot to
maximize upper DOS memory. Specifically, this setting (Award BIOS) is
called "Used MEM base addr=C800" and "Used MEM Length=32K". Anyone know
if this could impact framebuffer or "VideoRAM: 0 kByte"? Well, I turned
it off and tried startx again. The reaction has changed. The hatchmatte
or whatever it's called that comes up before KDE is now showing up
before the computer locks up, and the /var/log/XFree86.0.log now shows:

VideoRAM: 4096 kByte
Depth 8, (--) framebuffer bpp8
Loading sub module "fb"
Loading module "fb"

But also:
Open APM failed
System lacks support for MTRRs
Could not init font path element /usr/X11R6/lib/X11/fonts/Speedo, removing
        from list!
among other (WW)'s.

When I run 'XFree86 -configure' and follow that up with 'XFree86
-xf86config /root/XF86Config.new', X starts the same matte screen as
'startx', but it doesn't lock up the machine. I can even exit with
Ctrl-Alt-BS.

After reading in the XWindow-User-HOWTO, I tried from root 'kdm' This
got me a little further. After the gray matte backgroud pops up on tty7,
the screen color changes to Aurora's blue-gray, and then the shapes of
the login chooser paint, and some of its contents. The go, clear,
restart & shutdown buttons look complete, but unless I click on one of
the penquins, no other words appear, and except for the box with the
Mandrake star and the penguins, no colors appear except black & white.
If I click on shutdown, a new totally black window appears. If I switch
back to the session that started kdm, I can kill it.

If I try 'startx', the KDE splash screen comes up. Its first icon blinks
a few times, then the PC is locked up, hard reset required.

So, something remains undone. What is it?
