Thank you for the insult. I appreciate that considering I've never been
in contact with you.

Yeah, that was just an initial [second] quick hack...it appears that the
wrong version got patched in (ver 2, not 3).

That is correct...the bases[x]= above is not...
My intention was to put the insmod variables into bases[0],
setup_buson[0], setup_busoff[0], and setup_dmaspeed[0] so it would be
probed first...and if no variables, the above values (aha1542[] = { 0x330,
11, 4, -1 }) would be default.
