It would appear that on May 24, john brennan-sardou did say:

Well John, I can't say I've read all "forty-five page"s of the doc,
(didn't count them either) But when I let grub install itself for FC2
I told it to add entries for each of my linux. And they all looked like
your fedcore entry... And ALL of them got that error... I also noticed
that the rootnoverify & chainloader lines were used for the non linux
win98 partition (which worked for win98) And that convinced me to
quickly scan "info grub" for a few clues, then used the working FC2
entry as a guide to rebuild the other linux entries with some help from
my old lilo.conf for details like kernel names and clues what to append
to the kernel for it... After which the only thing I still can't boot
with grub is my DrDos hdc1 partition...<sigh>

My working FC2 & FC1 entries look like this:

title theWanderlust (2.6.5-1.358)
        root (hd1,3)
        kernel /boot/vmlinuz-2.6.5-1.358 ro root=/dev/hdc4 rhgb quiet
        initrd /boot/initrd-2.6.5-1.358.img
title theJourney
        root (hd1,2)
        kernel /boot/vmlinuz-2.4.22-1.2188.nptl ro root=/dev/hdc3 hdb=ide-scsi 
        initrd=/boot/initrd-2.4.22-1.2188.nptl.img

Of course I've never bought into the idea that root=LABEL was easier than
specifying the /dev/hd* <grin>
