Probably wrong kernel I was testing. I get, on an older kernel:
PNP: No PS/2 controller found. Probing ports directly.

So it would poke at it directly, which might cause hangs. The symptoms
is that, sometimes, the machine will hang on boot until I press the
power button, when it would continue.

Let me know if you know another way to blacklist the i8042 probing on
those machines...
