One cannot remove what is not present. What I did was block installation of
packages that the grub2 package does not declare to be required. Grub2 should
not be configured to show user an error resulting from its own installation
misconfiguration. That looks like a bug.

Why was it installed when I did 'urpmi --no-suggests grub2' if it's not
required?
# urpme os-prober
To satisfy dependencies, the following 2 packages will be removed...
grub2-yada
os-prober-yada...

What's wrong with nice legible BIOS native fonts?

</I>
Nice in theory, but the root device is off by -1. Default menu.lst cmdline
includes root=LABEL=22cauldrn instead of UUID or device name, which is
apparently disregarded by grub 2.
menuentry 'Cauldron defkernel' {
legacy_kernel '(hd0,22)/boot/vmlinuz' '(hd0,21)/boot/vmlinuz'
'root=LABEL=22cauldrn' 'splash=verbose' 'noresume' 'video=1152x864' 'vga=794'
'3' ''
legacy_initrd '(hd0,22)/boot/initrd' '(hd0,21)/boot/initrd'
}
It works when I s/hd0,21/hd0,22/g.

I saw no fonts in that progress bar. I asked for no progress bar.

grub2-menulst2cfg picked up the ones that work in Grub Legacy (vga=
((<A HREF="http://www.kernel.org/doc/Documentation/kernel-parameters.txt">http://www.kernel.org/doc/Documentation/kernel-parameters.txt</A>)) & video=
((<A HREF="http://www.kernel.org/doc/Documentation/fb/modedb.txt">http://www.kernel.org/doc/Documentation/fb/modedb.txt</A>))), which are kernel
parameters. They do the same thing loaded via Grub2 as when loaded via Grub
Legacy.

</I>
Booting with 3 on cmdline and later doing startx or init 5? On current boot I
used 3 on cmdline, logged in on tty2 & tty3, did startx on tty3, and found X
is running on tty3. On exiting the X session I did init 5. That put KDM on
tty1. On openSUSE & Fedora the problem is essentially the same, e.g.:

</I>

</I>
Maybe grub2-menulst2cfg should be used instead of grub2-mkconfig when grub2
is added to a system with grub previously installed.
