Three files have to be modified, and compiling a new kernel is required,
too, because linuxrc is one of those files.
Here are the files resp. the beginning of the files.
I'm using a modified rc.local (to free up some space, as posted earlier to
the list), but here I've taken an original and modified it.
Tested it with different kernel commandline parameters set in a
dhcp option - seems to be working.
