I can see there's a potential for a >conflict in this scenario because the keyboard controller driver is not >properly PnP-aware (it needs hints because it has to be up and running >early), but what you're saying doesn't seem to make sense. My reasoning is based on the bootverbose output from dmesg (included below from a system that doesn't exhibit the problem). On a Dell Optiplex GX110 which does have the problem, the PNP0f13 lines come before the PNP0303 lines (in the first section) and the keyboard probe messages (in the second section), and in the latter case (after "probing PnP devices") the PNP0f13 device grabs irq 12 before psm gets a look in. I don't have an Optiplex with FreeBSD on at the moment, sorry.
