Yes, that's exactly what I'm recommending.
On each drive:
fdisk -BI
bsdlabel -wB
bsdlabel -e
(set up partitions here, use a for root and d for stripe)
Then:
gmirror label somename firstdisks1a seconddisks1a ...
gstripe lable someothername firstdisks1d seconddisks1d ...
etc. There are obviously a few blanks in the above but the manpages for each
command and online documentation will help you fill them in.
