Just compile the driver with -DSKIP_BIOSTEST in the Makefile (add it to
the line AHA152X=), it shouldn't make a difference except if your board
is an AHA1510 (this is from the driver code, I did not know this board).
But it means that the system will directly probe i/o ports, which may be
dangerous.
