So btrfs is still not yet suitable to be a root/usr/var filesystem, even
in kernel 3.0.0?

Nope, still in heavy development, though you should upgrade to 3.2.
Also, the devs mentioned in several places it's not friendly to small
drives, and I'm pretty sure 5GB is considered tiny.
I don't think you need to separate /usr out to it's own disk. You could
instead create a single drive with multiple subvolumes for /, /var,
/usr, etc. When you have Ubuntu use btrfs for /, it creates @ and @home
for / and /home, respectively, so it's a common phenomenon if you look
for help.
