>Description:
	Both 5.1 and 5.2-RC1 are unable to "use" the installed floppy disk drive
	that 4.9 could/can use. Two boot messages appear in 5.x such as:

fdc0: cmd 3 failed at out byte 1 of 3
fdc0: cannot reserve I/O port range (6 ports)

	Under FBSD-4.9, the following boot messages are displayed that relate
	to the floppy drive:

fdc0: <NEC 72065B or clone> at port 0x3f0-0x3f5,0x3f7 irq 6 drq 2 on isa0
fdc0: FIFO enabled, 8 bytes threshold
fd0: <1440-KB 3.5" drive> on fdc0 drive 0

	Using loader.conf settings of "hw.pci.allow_unsupported_io_range=6", or
	with other values, makes no difference. While it has been awhile since
	I experimented with turning ACPI off in both the kernel and BIOS, I
	seem to remember that doing so also made no difference.

	Both 5.x and 4.x FBSD are running on the same machine, albeit off of
	different hard drives attached to an Adaptec SCSI controller.
