9.1 install wipes out gpart boot blocks?

I used gpart to set up a new disk,
then went through a 9.1 install.
Everything seemed to go fine, but when time came to boot the new drive,
it wouldn't boot.
When doing the 9.1 install,
I selected the disk and had to assign the partitions to the various filesystems.
AFIK, I did not otherwise modify the filesystems.
Does the 9.1 install process trash the boot areas?
My gpart setup was:
clean up (delete) the original partitions
gpart destroy ada3
gpart create -s GPT ada3
gpart bootcode -b /boot/pmbr ada3
gpart add -t freebsd-boot -i 1 -s 512K -l gptboot ada3
gpart bootcode -p /boot/gptboot -i 1 ada3
gpart add -t freebsd-ufs -a 4K -b 1M -s 4G -i 2 -l fbsdroot ada3 # /
gpart add -t freebsd-swap -a 4K -s 2G -i 3 -l fbsdswap ada3 # swap
gpart add -t freebsd-ufs -a 4K -s 2G -i 4 -l fbsdvar ada3 # /var
gpart add -t freebsd-ufs -a 4K -s 2G -i 5 -l fbsdtmp ada3 # /tmp
gpart add -t freebsd-ufs -a 4K -i 6 -l fbsdusr ada3 # /usr
newfs /dev/ada3p2 # /
newfs -U -b 4096 -g 8192 -i 1024 /dev/ada3p4 # /var
newfs -U /dev/ada3p5 # /tmp
newfs -U /dev/ada3p6
At this point:
gpart show -l ada3
=> 34 488397101 ada3 GPT (232G)
34 1024 1 gptboot (512k)
1058 6 - free - (3.0k)
1064 8388608 2 fbsdroot (4.0G)
8389672 4194304 3 fbsdswap (2.0G)
12583976 4194304 4 fbsdvar (2.0G)
16778280 4194304 5 fbsdtmp (2.0G)
20972584 467424544 6 fbsdusr (222G)
488397128 7 - free - (3.5k)
The / /var and /usr partitions seem to have been written properly.
Do I simply need to rewrite the boot areas,
or is something more fundamental screwed up?
