This is something I've been looking at off and on.  I think the best route
is to take quik and combine it with features from the integrated
bootloader and your preploader.  The current situation makes it tough to
offer a PReP distribution that smoothly installs since one needs to
rebuild the bootloader and link with the kernel just to change the default
root device and kernel parameters. :-/

I have working code for this that requires an updated PPCBUG revision.
A PPCBUG release with support for RBing PReP images should be available
"RSN", but it's hard to say since the firmware group is rather loaded
these days.
