Make i8042.c even less picky about detecting an AUX port because of broken chipsets that don't support the LOOP command or report failure on the TEST command. Hopefully this won't screw any old 386/486 systems without the AUX port.

would it make sense to at least printk() on such
broken chipsets?

Maybe. But if we wanted to printk() on every chipset which doesn't follow the i8042 spec in some way, we'd keep the logs full ...

If you keep it one line per bug, it should not be more than 2 lines on normal chipsets, right? :-). And we may get better hardware in future by doing this.
