Not sure about this. So far only Mint seems to trigger this problem, and only 
when reading from IDE. To notice that, you would need a machine with 68000 but 
IDE interface, and then run Mint&EmuTOS on it. I doubt that there are many 
users with such a configuration.

Concerning AHDI: looks like to access the IDE interface, AHDI uses the blitter 
if it exists. Not sure wether the blitter can do transfer to unaligned 
addresses. But if it is not present (unlikely, since machines without a 
blitter are either a TT with a 68030, or also don't have an IDE interface), it 
would use the same copy function as TOS -> bombs. There is no test for an odd 
address. Maybe Uwe can answer the question what HDDRIVER does in this case?
