Description of problem:
When I select manage kickstart and Advance options and I compare it to current options supported by Anaconda (anaconda-13.21.23-1.el6.x86_64) I got:

option "mouse" is no longer supported by anaconda
option "monitor" is depracated

And following options are new in anaconda and not supported by Spacewalk:

We may want to eventually somehow add it to Spacewalk.
