Yes, until this upgrade everything worked fine.

I think so; I've followed
http://www.daemonology.net/blog/2009-07-11-freebsd-update-to-8.0-beta1.html
and ran "freebsd-update -r 8.0-RC1 upgrade", "freebsd-update install",
rebooted, reran "freebsd-update install", rebooted and ran ndisgen.

Yes, I ran ndisgen and used kldload to load the generated module and
besides I copied the module to /boot/modules and tried loading it
after the kernel panics.
