Hi All.

It was clearly stated in the docs that I should have used the output of
'lspci -n' but somehow it supressed my attention. Sorry for wasting your
time on that.

On an other note, I've did what you and the manual suggested and here is
the result:

I needed to force my machine to reboot physically. Any suggestions are
very welcome.

(Ubuntu 6.10 - dom0 & domU - and Xen-3.0.3 binary install with Kodicom
4400R-like bt878 based DVR card)
Should you need more info on my setup, I'm happy to provide you with
that.
