I'm running OpenSUES 10.2 on a Pentium4 system

XEN and some guests.
One of the guests is a (opensuse 10.2) firewall with 5 NICs. Since we
have the limit of max 3 vifs' I'm exporting 2 with help of pciback. This
works fine most of the time but sometimes the guest doesn't find the 2
direct exported ports ("lspci" returns nothing). It seems to never work
if I reboot the guest and if I shutdown/create it works most of the time
but not always.
Done a complete reinstall on a different system with different hardware,
only os, config and problem is the same.
The other system is a AMD server and the NICs are two dualport e100
where I did a fresh install of OpenSuSE 10.2 (this time x86_64, otherone
was 32bit) and a new install of domU.
After configuring the pciback and testing reboot I got the same as
before, no extra ports after reboot of domU
I did compare dmesg after reboto vs after cold boot and found two lines
to be interesting
root@reed:~$ diff -u dmesg_after_cold-boot dmesg_after_reboot-boot

Why doesn't "pcifront" gets loaded after reboot ???
What loads/initialize pcifront ?
/ps
What can I do to make sure it always works?
Where should I look for the problem ?
Config data: On the host (dom0) I have
root@dom0# cat /etc/modprobe.conf.local
options pciback hide=(0000:03:02.1)(0000:03:03.1)
install sunhme /sbin/modprobe pciback ; /sbin/modprobe --first-time

bootloader = '/usr/lib/xen/boot/domUloader.py'
bootentry = 'hda1:/boot/vmlinuz-xen,/boot/initrd-xen'
On the guest I configured the network ports with "yast lan" and after
making the MAC static (it changed after each boot) it works whenever the
bypassed nics are available.
root@domU:~# cat /etc/modprobe.conf.local
options sunhme macaddr=0x08,0x00,0x20,0x00,0x00,0x49
Both host and guest runs a fully patched opensuse 10.2 -32bit
