freebsd stable - May 2010 - 8.1 Pre-release gpart, isn't setting type correctly

Performing the following gpart commands on either a hard disk or 
usb memory stick doesn't correctly store the gpart type information.

# gpart create -s GPT da1
# gpart add -s 1G -t freebsd-ufs da1
# gpart show da1

=>     34  7827325  da1  GPT  (3.7G)

Expected to see something like:

If I reboot the machine, only the /dev/da1 devices is recognised, there is 
no /dev/da1p1.  Also "gpart modify -i 1 -t freebsd-ufs da1" did not
have
any effect on the "gpart list"

We have a similar outcome when using the HDD,

Hardware: Used two different motherboards: Gigabyte (without ahci available)
and 
VIA SN1800 (with ahci available and enabled); two hard disks (WD500AAKS)and
one 
usb memory stick.

Initially I thought it was the ahci timeouts, but using different
motherboards, 
and a usb drive disproved that association.

If there is anything that I can do, or provide to help resolve this, I'm
happy 
to do so.

 This is probably the same issue reported at
 http://www.freebsd.org/cgi/query-pr.cgi?pr=kern%2F142174 and already
 fixed on CURRENT.  I guess the fix will be merged to 8.X soon.
