As usb devices become more used this will be an important problem.

For example, I want to create a usb flash drive for use in an
installfest, for people with no CD or floppy.

Partition 1 will have the kernel and initrd for the Fedora installation
process.

Partition 2 will have the same for Opensuse.

Partiton 3 the same for Mandriva.

Partiton 4 ubuntu.

How do I write a menu.lst to boot these different kernels with
different parameters, and partitions? I do not know which device the
usbstick will be at boot time, because the target systems have
different number of hard disks.

As matters now stand, there is no way to do it, and you seem to be
telling me the problem is not fixed with grub2!

It is easy to think of many analogous problems, in the comercial world.
