17 * Driver for the Logitech and ATI Inport Bus mice for use with 386bsd and
18 * the X386 port, courtesy of

20 * Caveats: The driver currently uses spltty(), but doesn't use any
21 * generic tty code. It could use splmse() (that only masks off the
22 * bus mouse interrupt, but that would require hacking in i386/isa/icu.s.
