[ES40-developers] Patch: updated fixes

[Brian W. <bdw...@in...>]

I went back through the ide stuff and renamed the semaphores and mutexes
to make a bit more sense.  In any case after making less-is-more locking
changes, VMS seems to boot ok, and I'm running an install right now.

There is an overall regression:  slave devices don't seem to be
recognized by freebsd, but srm sees them.
