Er, I phrased this poorly because we don't distinguish between
IRQ's and interrupts. Basically, we don't currently use
InterrupterDispatcher at all. This induces a hack in the keyboard driver
that will lose scancodes if >1 is generated per interrupt. This might be
'fixable' by re-implementing InterrupterDispatcher. However, I don't know
how much work this might entail, and as long as you're cloning the JavaOS
APIs for memory, I might as well clone the APIs for IRQs/interrupts.
(Rather, clone the parts that I need.)

Er, these virtual consoles are implemented entirely in Java, and
besides being "cool" (and wonderful for debugging), it's a good test of
the driver system. If the VGA driver ends up doing our text-display work
(and/or includes a text/video mode switch), I can use that method/code to
(help) handle switching the consoles.

Hey, great, anything that makes my job easier :)
