Xen users - Mar 2009 - Trouble adding a pci device to a a linux domU

Hi,

I want to give direct access to my monitor for my linux domU so that my
graphics can run smoothly inside domU which is Ubuntu 8.10
I tried doing the following, but things didn''t work out.

1. I boot my Xen on Debian ( lenny ) using
     kernel /boot/xen-3.2-1-i386.gz
     module /boot/vmlinuz-2.6.26-1-xen-686 root=/dev/sdc4 ro console=tty0
pciback.permissive pciback.hide=(00:02.0)
     module /boot/initrd.img-2.6.26-1-xen-686

I have added my pci device using the following config params for my linux
domU
    pci = [ ''00:02.0'' ]

lspci on my dom0 gives me
  00:00.0 Host bridge: Intel Corporation Mobile 945GM/PM/GMS, 943/940GML and
945GT Express Memory Controller Hub (rev 03)
  00:02.0 VGA compatible controller: Intel Corporation Mobile 945GM/GMS,
943GM/GMS, 943/940GML Express Integrated Graphics Controller (rev 03)
  00:02.1 Display controller: Intel Corporation Mobile 945GM/GMS/GMS/GMEm
943/940GML Express Integrated Graphics Controller (rev 03)
....

 I have tried changing pci to [ ''00:02.1'' ] but that didnt
help either. Any
clues to what can work out ?
