Possibly, but then we did use to have all interrupts disabled
at some stage before going to suspend_late anyway no ? So it shouldn't
make a big difference.

The VIA interrupt must not be HW masked in the PIC on some machines
because it's the wakeup source, so we may have to force re-enable it
since it can be lazy-disabled, but those aren't the machines with the
trackpad problem so I think I'll need to have a closer look at what's
going on and get my head around it.

Haven't had a chance yet, hopefully today or tomorrow.

Ben.
