Hello again...

I have found the d-i svn repository and attached is my attampt at patching
in the ideas I posted a few days ago.

I have changed the syslinux files in d-i/trunk/installer/build/boot/x86/
but I'm assuming these are only relevant to targets in
d-i/trunk/installer/buildconfig/x86.cfg

The changes are two fold...
(1) provide a pxelinux config for using the serial port.
(2) make syslinux/isolinux/pxelinux display the corect text on a serial
    console should they be talking to one. (ie: tell users "ctrl-F <n>"
    instead on the function keys "F<n>")

I have tested this by building and booting a testing/woody pxe-netboot
tarball and by building and booting a syslinux boot.img floppy.

The floppy boot worked as normal the serial-9600 pxe boot worked and
displayed the correct text.

Have fun!

Alex Owen
