I had the exact same problem a while ago on a 64-bit PowerPC and hacked
my way around it... (can't seem to find the patch now, though)... The
first thing you want to do is run:
brctl addbr br0
strace brctl addif br0 eth0
and look for what ioctl fails... Post that output and I might be able to
point you to the solution...
