yes, it works, I do it on my laptop all the time:
# format
Searching for disks...done
AVAILABLE DISK SELECTIONS:

selecting c0d0

[disk formatted, defect list found]
Warning: Current Disk has mounted partitions.
/dev/dsk/c0d0s0 is currently mounted on /. Please see umount(1M).
/dev/dsk/c0d0s1 is currently used by swap. Please see swap(1M).
/dev/dsk/c0d0s3 is part of active ZFS pool poolchen. Please see zpool(1M).
/dev/dsk/c0d0s4 is in use for live upgrade /. Please see ludelete(1M).
c0d0s5 is also free and can be used as a third live upgrade partition.
My recommendation: Use at least 2 slices for the OS so you can enjoy live
upgrade, one for swap and the rest for ZFS.
Performance-wise, this is of course not optimal, but perfectly feasible. I have
an Acer Ferrari 4000 which is known to have a slow disk, but it still works
great for what I do (email, web, Solaris demos, presentations, occasional
video).
More complicated things are possible as well. The following blog entry:
http://blogs.sun.com/solarium/entry/tetris_spielen_mit_zfs
(sorry it's german) ilustrates how my 4 disks at home are sliced in order
to get OS partitions on multiple disks, Swap and as much ZFS space as
possible at acceptable redundancy despite differently-sized disks. Check out
the graphic in the above entry to see what I mean. Works great (but I had to
use -f to zpool create :) ) and gives me enough performance for all my
home-serving needs.
Hope this helps,
Constantin
