From what I'm told, this is a pmon issue affecting all releases before 1.4.3.
If grub is booted via boot.conf on a system with a pmon version before 1.4.3 it needs args to contain something (anything) in order to successfully boot. Since this seems to be a pmon bug, unless its something that grub should work around, i guess this could be closed.

Can you compare pmon versions? GRUB ignores args altogether

I've just had feedback from someone else with a yeeloong. They say grub loads using this grub config:
default 0
timeout 0
showmenu 0
title Boot with GRUB
kernel (wd0,0)/boot/grub.elf

His grub version is the same.

Guess there is something else involved too.

This has some extra background info https://savannah.nongnu.org/bugs/?28759 in comments #2,3,4.

If using a pmon /boot/boot.cfg as follows, grub boots:

default 0
timeout 0
showmenu 0
title Boot with GRUB
        kernel (wd0,0)/boot/grub.elf
        args some-dummy-string

If your args line matches either of these, grub fails:
        args (no params
             (totally blank)

apt-cache policy grub-yeeloong
grub-yeeloong:
  Installed: 1.98~20091212-2
  Candidate: 1.98~20091212-2
  Version table:
 *** 1.98~20091212-2 0

Note on reproducibility: its every time, on the same machine. I'll post a comment when I can get feedback from someone else.
