The divas driver version can be found in the syslog messages when the driver 
is loaded.
I recommend to use the new V3 driver (ftp.melware.net).

When you start asterisk (with verbosity 5) you can see the chan-capi 
messages including its version. 
It's an too old version if it is from April, please update, same ftp-server.
