Arthur,
The problem does not seem to be due to your patch because
the bonding driver built without your patch crashes too on load.
However, the pre-existing binary under /lib/modules/`uname -r`/...
works fine.
Any idea why this may be happening ?
Given below is the output of trying to insmod the bonding driver.

Hmmm, interesting.
I've used it with 2.6.X for at least two values of X (one of them
being 5) so I'm surprised. Can you provide details about the oops?
