Don't worry about that. :-)

Did you use GRUB 2 CVS?

Right, the reason for that is that the firmware can't load from ext2 (or
whatever you use). So you need a HFS+ partition as /boot (assuming you use
an apple).

You need to have a new world apple or a pegasos II. Otherwise it just has to
work. If it doesn't, please describe exactly what you did and which errors
you encountered. It can certainly be the case that you found a bug; GRUB 2
is still not used that much and it changes and evolves rapidly.

I will write something for the wiki this evening or tomorrow, if nothing
is there about the organisation of the code. Otherwise I'll point you to
the
right documents.
