Thanks for all the help, Cromwell.

I don't have a forcedeth.kext and I've already tried -x...

I thought forcedeth.kext was a part of the drivers for NForce boards... My chipset is intel, and I added no extra packages during install.

Anyways, looks like this just isn't going to happen, I guess I'll just have to wait until someone else makes a 10.5.2 release.
