#1 lrmi doesn't work under freebsd 5.* or 6.0
Enclose is a patch:
- need to include sys/ucontext.h
- need to use sys/consio.h instead of machine/console.h
- /dev/mem can't be mmapped as private
Patch tested on 5.4 and 6.0 beta4.
I believe the change will work on older freebsd versions
and net/open bsd, however this is only from examining
the source code repositories, it hasn't actually be
tested.
Also get intermittent failures of vbetest on freebsd;
cause unknown, but I suspect it as vm_86 issue,
not a lrmi issue.

The private mmapped /dev/mem is for the interrupt vectors.
I'd prefer to have the effect of the private mapping to
reduce the chance of a null pointer reference destroying the
only copy of the interrupt vectors. Mapping /dev/zero and
copying from /dev/mem should be close enough.

I've applied your header file changes and reworked the
interrupt vector mapping. If you could test it for me that
would be great.

Seems to work great. Thanks a lot!
