I have one of these (AVA1505) in my drawer as the result of an
unsuccessful effort getting it to work here under a 3.0-current.

Interesting that you are saying that no irq comes through.
I observed that the probe was OK but when trying to
access the tape I had attached to it the process got hung which
may happen when no IRQ occurs. Also the aic probe seemed to
mess my WD8013 cards I had in that machine. After all I gave up
and bought a used AH1542CF. 

Maybe something's odd with enabling the interrupts on the board (aic chip).
