Sure. :-) Currently it's not possible to execute a KDL statement from another 
driver, you can just enter the debugger and the _user_ has to enter some 
commands. Therefore I added kernel_debugger_exec() which executes a single 
KDL statement and returns. This is supposed to be used by the emergency 

Additionally the output of these executed statements is routed to syslog too 
which is also not the default.
