I was going to try this out by copying the ISO contents to the running 
system, and started to do it. Then I remembered
1 /boot is too small
2 / is LVM. grub does not do LVM.
3. I don't really have any other place on the test system.

I could try it out under virtual pc except the f10alpha kernel doesn't 
boot under virtual pc. Some others do.

If someone has an easier system to test it on so they can document it, 
the procedure for setting it up was going to be this, adapted as needed:
1. Mount the CD/iso at /mnt/cdrom
2. Make a place to put the stuff: /boot/recovery would be nice.
3. Copy stuff. tar clC /mnt/cdrom | tar xpC /boot/recovery
4. Edit /boot/grub/menu.lst to mimic the isolinux configuration.
5. Test. Probably it won't find stage2. Investigate and hack until done. 
A symlink in /boot might be enough.
6. Delete unwanted files.
