Ah, right. Pegasos firmware does not pass the boot arguments, so GRUB 
cannot determine where to load its config file from. In fact, both the 
filesystem path and the partition number are missing, so there's really 
no way to guess the location correctly.

If you are using the latest firmware, you will need to remind the 
Genesi folks about this problem (I have CCed Sven). I have not heard 
when they intend to release fixed firmware, or maybe they have already 
and you just need to install the update.

I can't see any workarounds, since you can't pass any options to grub. 
I suppose you could hardcode "(hd,0)" as the default prefix in GRUB 
source... either that, or be happy you can use the "configfile" command 
(a feature yaboot lacks :).

This is another Pegasos firmware bug. suspend works, but resume 
doesn't. Luckily, in this case suspend is all we needed for debug 
information. :)
