Cool stuff !
I just merged it into the current CVS version and tested it on my 720...
I *sometimes* works. Somehow, maybe every 3 boot, my token ring card
starts up OK and interrupts are generated. The rest of the cases, the card
is detected, but fails to open and no interrupt is recorded in
/proc/interrupts. Is there anything special about the 720, like an
additional register which might have a random state at bootup time?
However, when trying to send IP traffic to the adapter, Linux immediately
crashes in csum_partial(). Looks like some more work is required to fix
the token ring driver.
