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.
