Can you build your own kernels?  (I assume so from the paragraph below :-)
You might want to try and grab Takashi's latest PowerManager patches...I
don't think they've been merged into the tree yet.  The URL can be found
in the Meta-FAQ.

I get the slot 9 thing, too.  Hmmm...I guess we'll have to figure out a
clean way not to probe slots which don't exist :-)

You might have to get a little more proficient with m68k assembly,
actually :-)  I believe that you can find the current FPE stuff in

/sys/arch/m68k/fpe

There's a README file which tells what's currently
implemented/unimplemented, but it doesn't describe the problems with
'LC040 support.  I think that either Allen Briggs or Ken Nakata have some
clue as to what's still wrong with 'LC040 FPE.

Later.
