OK, better spot: just after start_link(dev) around line 848 in tulip.c

	start_link(dev);
+	outl(0xf0000000, ioaddr + CSR9);

}

This worked on the PNIC2 card here.

I'm still playing with the CSR9 register to understand the semantics.
It's not as simple as just setting the upper four bits -- something
interaction is going on with the lower bits in the CSR9 register.
