Thanks everyone for the awesome input. I will be attempting another install
tonight giving the usb drive thing a shot, as well as seeing if the
partition is active. I'm sure I rebuilt the loader with
"LOADER_ZFS_SUPPORT=YES", as It wouldn't even boot the kernel before I did
this step. Alot of new things to try now, and Drew, I'm with you. I am
actually learing alot about the boot process as well.. it just sucks to
spend 10 hours in one day to have nothing work. :P
Thanks again everyone, I will post back with my results.
