Why not try and do it the right way ? You understand that what you do supposes
that someone else did the above thingy to create the original floppy, no ? So
since you can create it directly, why not do that ?

This is done at miboot floppy generation time, not at kernel compilation time.
Something akin to your perl script is neatly packaged in the miboot and
dependencies packages, so why not use it ?

hehe, floppies, ...

Indeed. Feel free to mail me (or a bug report maybe ?) your config with a bit
of descriptiion of what you tried to achieve, there is no reason the debian
kernel could not fit your need, i believe.
