Strange, should work. I would suggest to post your full kernel log,
maybe there is some enlightening message hidden.
I don't think it is a problem of your kernel version, but I'm able to
pass through devices on OpenSUSE 11.3 with
kernel-desktop-2.6.36-90.1.x86_64 from their kernel repository.

Exactly what server logs do you need. Is this only /var/log/messages or
more? And do I need to set specific options there?
Any other log files that you need?
dmesg> log-file
Before, generating these logs I will upgrade to a later kernel. As far
as I can tell, that will still be a 2.6.34 kernel. Perhaps I should try
the 2.6.36 kernel as well. Do you have the URL for the kernel repository
I should use? (cannot find an obvious kernel repository in YAST2).
http://download.opensuse.org/repositories/Kernel:/HEAD/openSUSE_11.3

I have attached the logs of /var/log/messages, dmesg, and qemu log
(other.log), as well as the kernel config parameters (/proc/config.gz).
I did the test with two kernels (see the tar.gz file): one kernel a
2.6.34 and the other a 2.6.36 kernel.
Comparing the dmesg with my kernel log, I'm missing messages like
[ 0.023960] DMAR: Host address width 36

Are you sure that you have an Intel chipset with the required features?
And have you checked that "VT-d" is enabled in the BIOS (or however it
may be called there)?
Jan
I have now done a PCI passthrough test on some real hardware. Supermicro
X8DTi-F motherboard (intel 5520 chipset), Intel Xeon L5630 processor. I
enabled Intel VT-d in the BIOS and them simply selected one of the
network interfaces for passthrough the the VM. And then... it just
worksd. Also, I am seeing output similar to what you posted above.
