I don't know how much help this will be, but here's my recent
adventures in setting up a bridge to use my netbook as a
wireless access point:

Here's where Dan Ritter suggested a bridge configuration that
worked for me:

It's a long story, and I think what I am doing is different from you're
trying to do, but something in there may be useful. (I was trying to
use etables and gave up, by the way.)

I'll note that the log messages were confusing. Even now, the bootup
messages say eth0 is not configured and isn't coming up, but the
bridge is functioning.

One of these days I'll get someone to pay me
to design a language that combines the best of Forth and C.
Then I'll be able to leap wide instruction sets with a single #ifdef,
run faster than a speeding infinite loop with a #define,
and stop all integer size bugs with my bare cast.
