Yeah, I'd get it via the fw_getenv utility.  There's an environment
variable called 'ver', that should be accessible.  I say 'should',
because I've never looked at it before and don't currently have access
to a Linux-booted board to verify.  I have used fw_getenv/fw_setenv
extensively to read and write other variables and have never had any
problems.
