problem with ite8875F to assign to domU

[Hans Morack]

Hallo,

the device is working without problems in the dom0, found from parport_pc: 

dmesg small2 snip:
	parport_pc: ITE8875 found (1P)
	parport0: PC-style at 0xf000 [PCSPP,TRISTATE,EPP]
	parport0: Printer, Kyocera FS-1700+
	parport_pc: ITE 8872 parallel port: io=0xF000
	parport1: PC-style at 0x378 [PCSPP,TRISTATE]
snap

to assign this device to a domU I gave the boot-parmaters pciback.hide=(00:08.0) 

dmesg found the folling lines snip::
	ACPI: PCI Interrupt Link [ALKD] (IRQs *23)
	Linux Plug and Play Support v0.97 (c) Adam Belay
	pnp: PnP ACPI init
	pnp: PnP ACPI: found 13 devices
	xen_mem: Initialising balloon driver.
	PCI: Using ACPI for IRQ routing
	PCI: If a device doesn't work, try "pci=routeirq".  If it helps, post a report
	pnp: 00:02: ioport range 0x400-0x47f could not be reserved
	pnp: 00:02: ioport range 0x500-0x50f has been reserved
	pciback 0000:00:08.0: seizing device
snap

the pci-device 00:08.0 is still found by the parport_pc modul the printer is working, 
I added the parport modul to /etc/modprobe.d/blacklist
shutdown all domUs and init 6 for dom0

afterwards dmesd small2 found snip:
	pciback: vpci: 0000:00:08.0: assign to virtual slot 0
snap

the device-line  pci=['00:08.0'] has been added to the domU configuration-file 

in domU with lspci snip:
	00:00.0 Serial controller: Integrated Technology Express, Inc. IT8874F PCI Dual Serial Port Controller (rev 01)
snap

in domU modprobe parport_pc
	dmesg in domU	parport_pc: cannot find ITE8872 INTA
in domU lsmod snip:
	parport_pc             33092  0
	parport                34120  1 parport_pc
snap

dmesg in dom0 snip:
	pciback 0000:00:08.0: Driver tried to write to a read-only configuration space field at offset 0x60, size 4. This may be harmless, but if you have problems with your device:
		1) see permissive attribute in sysfs
		2) report problems to the xen-devel mailing list along with details of your device obtained from lspci.

I'm running the ctserver2 with
