I reported this yesterday but somehow managed to mess up configs
and accidentally compiled 2.6.9 for SMP! :(
I just checked that it does not happen on non-SMP 2.6.9.
2.6.9-preempt is working too.
Here goes a problem description again.
I have an onboard VIA eth:

I booted with init=/bin/sh and ran 'ip l set dev eth0 up'
- it fails under 2.6.9-smp. This rules out my userspace setup
being somehow involved (for example, the fact that I rename iface
from 'eth0' to 'if' does not contribute to the bug).
My 2.6.9-smp config is attached.

My suspicion is that the eth0 device is not actually the VIA driver
at all. Since your config builds many drivers directly into the kernel,
probably one of the others created an eth0 device. There is no
guarantee of initialization order about which device gets created first
(at least the way network devices are done in 2.6).
You should investigate if there are multiple devices present
(ifconfig -a or ls /sys/class/net). Perhaps one of the other drivers
does not correctly handle the case of hardware not being present
and leaves a ghost behind..
One way to find out would be to look at:
/sys/class/net/eth0/device/vendor
/sys/class/net/eth0/device/device
/sys/class/net/eth0/device/subsystem_vendor
/sys/class/net/eth0/device/subsystem_device
