Thanks to Tim Kelly, I believe we have eliminated the possibility that
the L2/L3 cache is not being set up right in OF.

Many thanks to Tim, who helped me run some tests with his new ofwboot.xcf
code, and reminded me that we can telnet to OF (Cool!) for debugging.

On this "upgraded" machine, the "while(1)" program running in the
background makes the machine quite stable.  If I kill it, then
the machine freezes up the next time I try to do any interesting
network activity.  This seems to be the same with the 3Com and the gem
(built-in) ethernet.

Any other thoughts from anyone?
