Of course, we could just decide to try to switch from level to
edge-triggered if the irq storm thing ever triggers. Right now we disable
the irq entirely, which means that _if_ it was just due to a polarity
error, we're screwed even if it should have been easy to fix by just
turning it into edge-high.

The code to do that should be trivial: make __report_bad_irq() try to
switch to edge mode if it's not edge already. Hmm?
