Ah hem, "bios". Do we trust that hunk of proprietary code now? Note
also that pc_keyb.c allowed for embedded devices where there is no BIOS.
That said, not sending 0xff seems to be fine on the keyboards I have
here. I wouldn't like to guarantee that it's fine across all keyboards
though, just like sending 0xAA on reconnect isn't guaranteed.
