I just installed grub from ports and duplicated your test and it works 
fine.  I'd start by checking your installation and making sure you don't 
have any other grubs in your path.  Some of the grubs that ship with 
Linux distros do not support ufs.  Do a find/locate on grub to see what 
turns up.  Do a which grub, you should get /usr/local/sbin/grub.  If 
not, issue /usr/local/sbin/grub from a command prompt and duplicate your 
test.  If that's broken, make sure your ports tree is up to date, make 
sure /usr/ports/devel/autoconf259 /usr/ports/devel/automake19 
/usr/ports/devel/gmake are up to date (grub's build dependancies) then
deinstall, clean, and reintsall the grub port.
