I hadn't looked at it that closely. However, that sounds like it's asking
for trouble. The BKL has been pretty heavily deprecated in 2.6. There
have been a ton of changes to irq handling as well.

I'm not sure if it is still the case, but in the copy of the tree I
have handy, atari_scsi uses a local copy of NCR5380.c rather than
the shared copy being used by mac_scsi. The sun3_scsi driver appears
to have a local copy as well. I wouldn't trust the atari driver working
as being much of an indication because of this.

I have to admit to lacking information with some of the SCSI specific
issues. In any case, it would certainly be good to test the Atari code.
