The only bell this is ringing is regarding the new mouse acceleration code.  
There was a bug in some versions of FreeBSD (maybe Open and Net too) where 
FPU context wasn't being properly saved or restored on signals, so since the 
mouse code runs from SIGIO occasionally you'd get bogus FPU state and the 
mouse would slam against an edge.

I think Matthieu said they had a regression case for it now, might want to 
make sure netbsd passes it.
