this is not actually surprising.  there are only about 3 majors which

move around without problem.  It is a MD detail, which is why tables 
have
to know about it
ok

I sometimes wish we'd split the majors into MI and MD "ranges", but 
that'd need a giant flag day and I can't motivate myself to do the work 
for that.

Anyway, the diff is ok kettenis@ as well

Major 30 is taken on both platforms, so use 32 to give a chance for
people to use dt(4) and btrace(8) on these platforms.

Ok?
