What sort of bonding are you using? PVFS shouldn't mind whether the
bandwidth is delivered by one network card or multiple if the bonding is
transparent.
You may be able to confirm what baseline throughput the bonding is
delivering using netpipe.
There is no way to make the connection between a single PVFS client and
a single server use more than one socket at a time.

How are you copying? The version of coreutils in debian etch
(5.97-5.3) will use a very tiny blocksize in some situations. Is
pvfs2-cp any better?
OK, I've tried writing using pvfs2-cp, rsync and dd, and network
thruput reaches 120MB/s, so it's definetely more of a cp probem :)
Another thing : I'm using bonding to aggregate bandwidth but pvfs2 uses
only one link, probably because pvfs2 uses only one socket; is it
possible to force it to use two or more connections when there are
several IOs going on?
