I just committed some changes to the tulip driver that should let you
read a MAC on the bultin tulip on the A180 -- please let me know if this
doesn't work on other machines.  You need to apply the attached patch
since check_region doesn't understand our fudged PCI I/O addresses.  You
can type "in la" from the boot menu to get the MAC of the builtin lan
adapter.

I suspect that the tulip code is still broken on pa20 boxen because of
the fudged addresses.

Thanks to Grant for fixing the Dino code that I was having problems
with.
