It turns out I am an idiot.

At some point, I got confused which btrfs trees I was working in,
and gotten switched up to where I had insmod'ed btrfs v0.13, but
was trying to mount a filesystem created with
btrfs-progs-unstable. Of course, I got a version mismatch when it
went to check for BTRFS_MAGIC and mount failed.

Moving to btrfs-unstable allowed me to mount the filesystem.

[root at canola btrfs-unstable]# mount -t btrfs /dev/cciss/c2d1
/mnt/btrfs
scan one opens /dev/cciss/c2d1
found device 1 on /dev/cciss/c2d1
lowest devid now 1
scan one closes bdev /dev/cciss/c2d1
opening /dev/cciss/c2d1 devid 1
lowest bdev /dev/cciss/c2d1

Sorry for the noise.
