Well ideally it would be a per-device option. This would help the ide SD cards greatly and people could byte swap their devices one at a time.
Would a byte-swapping IDE cable help, e.g. if the same flash memory card was moved from an IDE interface to a SCSI interface (on the same Q40)? Perhaps we should not worry too much about unusual use-cases during what would be a temporary transition period...
Think of it, if you want to boot an older kernel you don't want to byteswap your whole hard disk back and forth every time when testing an older or newer kernel.
Probably not an issue for end-users, as they are more likely to boot an old userland together with an old kernel. But potentially an issue for kernel developers who need to mix new kernels with old userland. However, kernel developers can use out-of-tree code to help with their testing, as usual.
