I'll add that, but it's only a partial fix: what if ehci_hcd is loaded 
before the forcedeth driver?

Luis, could you apply the patch and boot with it? It should print 
something like

forcedeth: irq line 11, Status 0x00000020, Mask 0x00000020

If mask and status are really not zero, then it explains your problems. 
Additionally I try to reset the nic in nv_probe - there were a few 
reports seemed to indicate that the nic generates timer interrupts even 
if the mask is zero.
