[Bridge] Bridge support unavailable

Yep!
First lsmod I got no bridge. Second lsmod after modprobe bridge I got
bridge listed. So here comes the $35 question. How do you make the
module load at boot?
After Googleing modprobe, lsmod, insmod there seems to be know way to
use modprobe to load modules at boot. I came across discussion to add it
to modprobe.conf but others said this would not cause it to load at
boot. Another mentioned rc.local but I'm not sure that rc.local will
load at the right time. On the other had that may not matter but I'm in
to cleanliness.

Any suggestions?

Bert,

Some init script that is trying to execute brctl and causing your error.

  Finding that script can be... interesting.

One thing you almost certainly want to check is to see if bridge.o is 
being loaded.  Use lsmod as root to see if it's loaded.  If it is 
loaded, then you almost certainly won't need to rebuild the kernel.  If 
you don't see it loaded, try modprobe bridge and re-check with lsmod. 
If it loads, again, no kernel rebuild needed.
