It was working in 2.6.9-rc3.

drivers/net/via-rhine.c did not change between rc3 and "official" 2.6.9

Is your ethernet device really named "if" not "eth0". You must be
using nameif or something to rename it.

Perhaps the name isn't what you expect.  Look at things like: 
	ifconfig -a
and
	ls /sys/class/net

What ever you are using to assign the name "if" to the device is (which defaults to eth0)
probably got confused
