This patch should be ok, I think, but I think it needs to be send to the
list before going to lkml. If you have any comments, please speak up.

If the driver has interrupts available to it, there is really no
reason to have a kernel daemon push the IPMI state machine.
Note that I have experienced machines where the interrupts do
not work correctly. This was a long time ago and hopefully
things are better now. If some machines still have broken
interrupts, a blacklist will need to be added.
