Hi Dave,

Firstly, sorry for the delay.
Here's another attempt.

An example:

crash> linux_banner
linux_banner = $3 = "Linux version 2.6.32-220.28.1.el6.x86_64 (mockbuild at x86-022.build.eng.bos.redhat.com) (gcc version 4.4.6 20110731 (Red Hat 4.4.6-3) (GCC) ) #1 SMP Wed Oct 3 12:26:28 EDT 2012\n"

crash> mod -T
