Subject: Config change by patching FreeBSD kernel binary possible ?

A very fine feature of the FreeBSD 2.0R bootfloppy kernel is the -c option,
which allows to adapt IRQs, IO addresses, and other parameters in the booted
kernel to the physical reality.
Now after finding out the right reconfiguration it would be even finer, if
there were a kernel binary patch utility to make these changes permanent
without the need for a recompilation of the kernel, so that for later
bootups from a harddisk the -c option need not be repeated.
Would that be possible, does that utility perhaps exist already ?
Just an idea,
