On the client system:
# cat /sys/class/infiniband/mthca0/ports/1/lid
0x2

On the server system:
# cat /sys/class/infiniband/mthca0/ports/1/lid
0x3

modprobe ib_cmpost "slid=0x3" "dlid=0x2" "message_count=0x10" 
"message_size=0x100"

Yet on the client:

root at delta:~# dmesg |tail -n 10
NET: Registered protocol family 10
Disabled Privacy Extensions on device c033a200(lo)
IPv6 over IPv4 tunneling driver
eth0: no IPv6 routers present
ib1: no IPv6 routers present
ib0: no IPv6 routers present
cmpost: starting client
cmpost: connecting
cmpost: failure sending REQ: -22
cmpost: test complete

So, it's not something simple like the LID's not matching. Of course, 
that doesn't rule out that I'm not doing something else stupid. :)
