	I am sad to say it has some problems.

# SHARP Mebius MURAMASA PC-MT2-F1 (i830MG chipset)

	1. After this patch was applied, Cardbus/PCMCIA is not available.
	   I tested following Compact Flash card.
uart0: <HONDA ELECTRON CO.,LTD BMH10C-J> at port 0x2f8-0x2ff irq 10 function 0 config 9 on pccard1

          | hw.pci.allow_unsupported_io_range = 0  | = 1
----------+----------------------------------------+-----
on boot   |                   NG                   | NG
----------+----------------------------------------+-----
any point |                   NG                   | NG

	on boot = card was inserted on boot.
	any point = after boot, card was inserted.


	2. Firewire is not available on hw.pci.allow_unsupported_io_range=0.
fwohci0: <Ricoh R5C552> mem 0xe0202000-0xe02027ff irq 10 at device 0.2 on pci2
fwohci0: Bus reserved 0x800 bytes for rid 0x10 type 3 at 0xe0202000
fwohci0: OHCI version 0.0 (ROM=0)
fwohci0: invalid OHCI version
fwohci0: FireWire init failed
device_probe_and_attach: fwohci0 attach returned 5

	3. USB EHCI is same too like firewire.  But I don't use it...
usb2: EHCI version 0.0
usb2: wrong number of companions (0 != 2)
ehci0: USB init failed err=13
device_probe_and_attach: ehci0 attach returned 5


	Unfortunately, my note can't resume S3, yet.
	I affix dmesgs of 1's pattern, and acpidump -d -t.
