I'll do that (and test the old falconide driver with your patch - never 
got around to that, and I now remember there was something fishy in that 
driver in relation to registering the IDE interrupt that I need to 
re-check).

Looks like that's commit e4ab3dc4eb88f53730061a3976c1e63523c5567d which 
fixed the conflict for me, thanks.

Neither have I, but I'd like to verify that the falconide driver still 
works with SCSI after this patch (can't see from the diff what the 
ramifications are for locking and request_irq() ... as I said, I 
remember something odd about the IDE interrupt that I need to verify).
