According to ugen man page, ugen can be compiled into the kernel with
device ugen
in config file.

I tried that in the kernel config when upgrading from FreeBSD 9.0-RC1 to RC2, but the kernel build stopped quickly with the message that ugen was not valid.  After removing that line from kernel config, "make kernel" was successful.

I didn't find "device ugen" anywhere in the conf/NOTES or conf/GENERIC files.
