I basically don't understand how the information from lspci, dmesg,
and /proc/mtrr is used to determine optimal values for xorg.conf
VideoRam and /proc/mtrr itself.  I hope that doesn't offend anyone.

Don, your command worked great, although I did leave out the |
character.  I now have this.

system1 ~ # cat /proc/mtrr
reg00: base=0x00000000 (   0MB), size= 128MB: write-back, count=1
reg01: base=0x08000000 ( 128MB), size=  64MB: write-back, count=1
reg02: base=0x0bf00000 ( 191MB), size=   1MB: uncachable, count=1
reg03: base=0xf8000000 (3968MB), size=  64MB: write-combining, count=1

My video driver's source says if I leave out the xorg.conf VideoRam
attribute, it will figure it out on its own.  Would you specify your
own value?

Here is lspci -v:

00:01.0 VGA compatible controller: Intel Corporation 82810E DC-133 CGC
[Chipset Graphics Controller] (rev 03) (prog-if 00 [VGA])
        Subsystem: Intel Corporation Unknown device 4332
        Flags: bus master, 66MHz, medium devsel, latency 0, IRQ 11
        Memory at f8000000 (32-bit, prefetchable) [size=64M]
        Memory at ffa80000 (32-bit, non-prefetchable) [size=512K]
        Capabilities: [dc] Power Management version 1

and dmesg:

agpgart: Detected an Intel i810 E Chipset.
agpgart: detected 4MB dedicated video ram.
agpgart: AGP aperture is 64M @ 0xf8000000
...
I810FB: Video RAM   : 4096K

Thanks a lot for your help.
