-------------- Cutting a lot of good stuff---------------
Here is what I got with the above command.

root@fpac-dev:~# /sbin/lspci -v |grep -i bridge
00:00.0 Host bridge: Intel Corp. 440BX/ZX/DX - 82443BX/ZX/DX Host
bridge (rev 02)
00:01.0 PCI bridge: Intel Corp. 440BX/ZX/DX - 82443BX/ZX/DX AGP bridge
(rev 02) (prog-if 00 [Normal decode])
        Memory behind bridge: f8000000-fbffffff
        Prefetchable memory behind bridge: dff00000-dfffffff
00:05.0 Bridge: Intel Corp. 82371AB/EB/MB PIIX4 ISA (rev 02)
00:05.3 Bridge: Intel Corp. 82371AB/EB/MB PIIX4 ACPI (rev 02)

I have the machine back to 64M so that I can run X and at least get a
few things done
there. The impact appears to be only on X. I do mostly command line
stuff on that
machine, I am setting it up for a switch demo, but at the same time
would be nice to
be able to run X on it at a better speed than what the 64m allows.

Here is the dmesg dump
