I'd strike the 'almost' in the last sentence. ;-)

Actually, this is very similar to what you can get with fVDI if you don't
let a device driver do the mouse cursor drawing.
The problem then is that the drawing of the cursor takes too long, so the
interrupts will still be turned off when the next mouse package arrives
from the keyboard processor.
I'm not saying that exactly this is your problem (that would be quite
unlikely), but make sure you don't have anything installed that might turn
off interrupts for 'long' intervals.

Either that or there's something slightly wrong with the NOVA hardware or the
connection to it.

Sure sounds like it to me.
