SubjectRe: test10-pre1 problems on 4-way SuperServer8050

If MTRR support is disabled then both eepro100 interfaces work fine but
the system is still 40x slower. This is the entire bootlog of
2.4.0-test10-pre1 + lspci-vvx + /proc/interrupts + /proc/iomem + ifconfig
output

Two currently active ideas (from Mark, Linus and Zoltan):

a) one needs to use big-mtrr patch from Zoltan, look at e820 map and
manually set up mtrrs to cover all 6G.

b) this is an L2 cache-tag issue and there is just not enough bits in the
tag to cover such high addresses so nothing will help, save removing the
extra 2G or so out of the machine (or using them as MTD devices :(((( I
hope this is _not_ the case...

another idea (in parallel) is that eepro100 stops working because its PCI
memory space is marked as cacheable.

All should become clear soon -- I will spend the whole day on this, slowly
trying to understand what's going on.

Tigran
