just for clarification: the kernel didn't stopped at all. It is
"nitpicker", the windowmanager, that tried to get a session to the
framebuffer driver. As there is no such driver available, when asking
its parent process, "nitpicker" got a "Service_denied" exception in
return. The "nitpicker" initialization code doesn't catched that
exception, that's why c++ exception handling code printed the uncaught
exception name and called the abort routine. Therefore, it's not the
kernel, but nitpicker that stopped.
