you will also need the filesystem type ( e2fs_stage1_5 or xfs or reiserfs,
etc )
you will also need to know how to create grub.conf and menu.lst and
devices.map ( a correct one, that you know what to change to make it
work on your system -- depending on where you built vmlinuz and
what disk/partition you are trying to boot on the target system )
making a (properly working) grub boot floppy is very tricky biz..
you should know how to make:
- a standard boot floppy: dd if=kernel of=/dev/fd0 ..
- lilo boot floppy: lilo -C /etc/lilo.fd.conf where boot=/dev/fd0
- syslinux boot floppy
- than try a grub boot floppy

dd if=/dev/working-grub-device of=/dev/fd0 bs=446 count=1
where working-grub-device is for example: /dev/hda
