OK, that's wierd.  Why on earth isn't it showing up in 
/proc/interrupts?  It's certainly generating Tx interrupts,
and the ISR is being called.

Is this a new NIC?  3Com have just started shipping a
new flavour of the 905c, the 3c905CX.  With this device
the RxReset command takes tens of milliseconds to complete,
not tens of microseconds like all the others.  This
breaks the driver.  You end up being able to transmit but
not receive.

And the old media interface selection algorithms don't work
right with the 3c905CX either.   We only got this sorted
a few days ago and we missed the 2.4.0 boat :(

Could you please test this 2.2 driver?
