Running DevFS is truly beyond me

You possibly missed something in the kernel compile, just because DevFS daemon is starting, doesn't mean for sure that you didn't miss something vital in the kernel (possibly in the filesystem's section?). And with DevFS those devices don't exist, they are merely symlinks to the actual device which is something like /dev/lun0/drive0/lots0/stuff0/hd0 only not that, but I think that displays something like it
Anyway, what I'd do right now is learn about the DevFS deal, see if it's something you've overlooked and try to rebuild your kernel and include that if you didn't.
Cool
