>Description:
	The loader tunable hw.pci.allow_unsupported_io_range hasn't
existed since src/sys/dev/pci/pci_pci.c 1.29 (imp, 11th Jan 2004). The
loader documentation still mentions this tunable.

>How-To-Repeat:
	man 8 loader or view the help pages from the loader itself.
>Fix:

	(Patch also at http://www.devrandom.co.uk/freebsd/loaderunsuppio.diff )
