GPT support?

[Nick Sayer]

I've got a 7.0-RC1 system and am setting up a 1TB USB drive on it. I'd  
like to set the drive up with a GUID partition table. I've used the  
GPT utility to create the GPT label and the partition, but though GPT  
says that there's now a da0p1 partition, I don't see a /dev node for it.

I'd assume that I'd need to load a GEOM module for GPT.... but I don't  
see one. It hardly seems possible that GPT support isn't there... What  
do I have to do?
