I looked at the console output you sent me and I saw several things
not correct (which I'm trying to fix) right away:
o I/O BAR's where not getting programmed correctly.
(both tulips fighting for the same I/O Port address (0) caused the hang)
o command register was not set
o cacheline size and latency timer were not getting set.
Now I have the opposite problem: PCI code finds and initiliazes the
tulips behind card-mode Dino but tulip.c doesn't want to talk to them.
So I can't really say for sure my changes work.
I've committed my code anyway since the oboard tulip continues to work.
Perhaps you can take another look at this.
