I'm not sure. If I was a driver writer (and I'm happy those days are
mostly behind me ;), I would not be totally dis-inclined to check for
various limits and things.
There can be hardware out there that simply has trouble with non-native
alignment, ie be unhappy about getting a 1kB request that is aligned in
memory at a 512-byte boundary. So there are real reasons why drivers might
need updating. Don't dismiss the concerns out-of-hand.
