Without knowing the exact kernel version your using we can't either.
You may be able to read something from it (and make our life easier)
if you used xenctx's -s option (passing in the System.map that matches
the kernel used in the guest).

Hmm, yes, that's ugly. I have always been advocating for modular
drivers...

I'm not aware of one, but we surely had found some way to use PV
drivers in 11.4 guests, just that I don't recall the details - hopefully
others reading the list will.
