Or a manufacter specific directory (dev/dec, dev/sun).  Anyways, there
should be a dev/apple for macppc/mac68k code sharing.

Anyways, pmioctl.h should die in favor of wscons but it really should
move to dev/dec since (surprise!) the VAX X code uses similar mechanisms
and I see no reason why both should not share that file?

Which is one reason dev/qbus exists. :)
