I see you're cozying up, good :) I don't think resetting through the 8042 is
that easy though. In QEMU, when I reboot this way, the keyboard stops working

Nope! But if you type before the information thingy "Dusk OS XXXXKB used

On osdev, I see some references to A20 line caveats.

Also, I wouldn't add such convenience the the "poll" driver. That driver is only
there for hardware debugging purposes and shouldn't include conveniences. The
real 8042 driver is the IRQ-based one.
