Yes, if that IRQ works...

I suspect that the Tulip problem is related to this one.

The card is reporting that packets have been received, but the interrupt
handler has not run.

You can transmit four packets before the interrupt handler must run to
recover the entries.  So you can get the initial discover out, but you
never see the offer nor could you reply with a request.

I'm not certain of the details of your problem, but it's a IRQ mapping
problem,  not a driver problem.
