I had the same problem, and root cause is that the RC2 installer
created and s0 slice that didn't use all of the available space.
The last "cylinder" on the usb flash media is unused. I had
previously installed RC1 on the same flash memory stick, so
there is still some old zpool label data that can be found via the
s2 slice on the last cylinder.

Apparently this is a known problem:
http://defect.opensolaris.org/bz/show_bug.cgi?id=5284
TI doesn't utilize last cylinder when creating VTOC with default layout
To get rid of the second corrupted "rpool" on slice 2 I created
a new slice in the format utility for the last cylinder. I used slice
s7, with start cylinder 3820 and size of 1 cylinder. After that I
scrambled the contents of that last cylinder with
dd if=/dev/dsk/c?t?d?s7 of=/dev/dsk/c?t?d?s7 conv=swab
Now "zpool import" finds exactly one "rpool" on the usb flash memory
stick, on the s0 slice.
