Couldn't reproduce the problem anymore (kvm e.g. might not be a good test
candidate as well for such stuff, JFTR), credits for testing to Jimmy. Closing
this bugreport therefore.
At least starting with release 2009.10 the caps-ctrl script doesn't seem to
work reliable anymore. Needs work so it works both on console and X as it used
to work before.
Note1: caps-ctrl should work on older grml/Debian versions as well as on
current ones, so it should be tested at least with different version of grml-
daily-ISOs.
Note2: also check out http://bts.grml.org/grml/issue382 when touching caps-ctrl.
