Well, I'm assuming you're using Orca or APW C?  Why not make a tool call to
SetVector (I think that's the name) to patch "keyboard interrupts," and then
make another call to IntSource to enable "Keyboard Interrupts."  I put this
in quotation marks, because there isn't such a thing, but it is simulated
by the firmware by using the Heartbeat Queue and VBL interrupts.
