Have just compiled a kernel package from James' tree directly, rather 
than attempting to back-port and manually patch, so I'm now running 
2.6.32-rc4 with mptsas 3.04.13.  I'm running the smartctl -a in a loop 
at the moment and will leave it running over-night, but with this kernel 
I get a pair of messages like this:

for every 'smartctl -a /dev/sg1' command which is run.
