It worked!

A bit of a pain to make a bootable grub CD. Here's an outline:
1. get legacy grub from gnu.org using cvs
$ export CVS_RSH="ssh"
$ cvs -z3 -d:ext:anoncvs@savannah.gnu.org:/cvsroot/grub co grub
2. configure and make
$ cd grub
$ ./configure /* lot's of options; see --help; I used no options */
$ make
$ ls
3. create boot floppy
Note: luckily I have a desktop Linux box with /dev/fd0
$ su -
# cd /home/user/grub/stage1
insert floppy
# fdformat /dev/fd0 /* important; I seem to have lots of bad media */
# dd if=stage1 of=/dev/fd0 bs=512 count=1
# cd ../stage2
# dd if=stage2 of=/dev/fd0 bs=512 seek=1
4. create file image of floppy
# dd if=/dev/fd0 of=boot.img bs=10k count=144
5. create bootable ISO form floppy image
# mkisofs -r -b grubboot.img -c boot.cat -o grubboot.iso ./
6. create CD using grubboot.iso

Another layer of magic peeled back. More _power_.
I was able to boot OSs in both the ntfs and ext2 partitions. The Woody
install continued on its merry way.
