[PATCH] ipmi: don't start kipmid if the IPMI driver can use interrupts
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.
