>Description:
	Asus hides the SMBus PCI bridge within the ICH2 or ICH4 southbridge
	on  Asus P4B533/P4PE mainboards. So ichsmb driver doesn't detects
	SMB bus.

>How-To-Repeat:
	Include
	    device	smbus
	    device	ichsmb
	    device	smb
	to the kernel config file, recompile kernel and reboot.
	New kernel will not detects SMB bus.
	pciconf -lv will not list it too.

>Fix:
	There are linux patch.
	See http://www.cs.helsinki.fi/linux/linux-kernel/2003-11/0868.html
	for details.
