That doesn't sound good.

Anyone with a suitable Atari, i.e. ATARIHW_PRESENT(TT_CLK), who can boot 
both TOS and Linux could resolve the question. (Perhaps with an emulator?)

Any old kernel binary would do, since atari_scsi should print either 
"HOSTID=n" or "this_id n" at startup.

If n doesn't agree with what TOS says about the host's SCSI ID, then I 
think a trivial patch is safe enough. Especially if cat /proc/driver/nvram 
produces a "SCSI host ID : m" that does agree with TOS.
