They work by turning off the 0th bit copy used to simulate the 9th bit position on the VGA fonts. I believe Kazu has incorporated my patches for these modes into -current (I originally wrote them for 2.2.6 syscons). So in response to the original question: sure you could move the mouse chars to 0x08 - 0x0b if you wanted, but it'll look bad unless you are running in a 90-column text mode. In any event, If we don't here from Kazu in the near future, I'll send-pr a patch to make the first character used for the mouse cursor a sysctl knob.
