For now would it be ok to just fix the reschedule flag for 68000 (i.e.
I send a v2 that loads a single byte instead as you suggested). That
would at least make it usable for me and the other few strange people
using it. :)
I have poked around at converting 68000 to the generic entry stuff. I
think that would make most of this custom asm go away... but it'll
take a while before its ready.

Thanks,

Daniel
