Sure. It's attached.

It doesn't find the root filesystem if I omit the root option from the
kernel command line.

I don't believe any of this is related to the problem. Anyway. The
setup is exactly the same that Hollis described in his original
report. The only thing I do manually after installing a new kernel
image package is to dd the vmlinuz file onto the PReP boot partition.

Please keep in mind that *my* PReP system is running fine now, after
numerous bugs that I reported have been fixed. I'd rather just set
that root option, the ideal way being the bootargs patch, and then
move on to more worthwhile things.
Such as getting my recently acquired R50 and the Thinkpad 860 running :)
Regards, Jens.
