I see.

I'm pretty sure it could, but there is no reason why it would have to be
crippled in that way. Interrupts should work perfectly fine with IDE on
Q40.
There is another reason why using the same module binary for both might
fail - the awkward address translation code in io_mm.h. Not certain at
all whether we can even have Q40 and Atari in the same kernel binary...

Not sure what the defaults are - pata_buddha.c and pata_gayle.c use the
same code in their _set_mode(). I suspect we'd need it for Q40, too.
Cheers,
Michael
