The current version of the loaded Zaptel modules (works as of kernel
2.6.12 or so) -

  cat /sys/module/zaptel/version

The version of the installed module:

  modinfo zaptel | grep ^version

Generally, no. But where exactly do you see that?

My system has 182232 kB free, not just 8016 kB. The extra free memory is
used by the system for improving access to the hardware rather than
being wasted. 8016 kB are being wasted right now.

In short: look at the second line at the output of 'free', or do the
math yourself.
