Yes, there is only the one. :-)
There is something weird with netback. The last time as I was using
netback from the hackery tree (around 2.6.29-rc8), I got extremely poor
network performance (like 2MB/sec), now I'm getting about 60-100 MB/sec,
which is a lot better. These numbers are obtained from just running
ttcp between the dom0 and a domU (the domU I tried was both with an only
non-pv 2.6.18 and a recent 2.6.29 pv domU kernel). It still only uses a
very small amount of CPU and I didn't see any changes mentioning
performance issues.
