Note that Control-A will only cause entry to the kernel debugger
after the serial port has been opened for the first time (e.g. by getty); 
prior to that, you must use the 'kdb' flag on the LILO line and set
breakpoints at appropriate points in the startup code.

Note also that many module symbols will not be available to kdb as they
aren't exported by the module loader commands.
