I can confirm that gstripe doesn't have to work only with whole disks. 
I am using gstripe on a 5.3-BETA7 system to stripe across two slices
(ad0s2 and ad1s2 on two ATA drives; I am using geom_mirror across ad0s1
and ad1s1).

Actually, I labelled the two stripes using glabel(1) and am in fact
striping the two labelled providers (so I can freely move the disks
around without breaking the stripe).

I do recall some people reporting synchronisation problems using
geom_mirror with SCSI providers (with Pawel providing various patches to
fix things).  It's possible the same problems affect geom_stripe
devices.

Cheers,

Paul.
