The question is if the card is configured to issue int10 and 11 for
sio1 and sio2.
The probing sounds like you get no interrupt at all, but since the int
probing waits for unassigned interrupts the test may fail for special
systems or BIOS setups.

Test tranfering data at any speed and check vmstat -i output if you
got interrupts for it.
