Short answer: nope :-)
That's not correct, if you would have read the description of the task 
you would know that the stage 1 boot loader loads the OpenBeOS "zbeos" 
equivalent from a BFS disk. Now, adding support to GRUB to be able to 
load from BFS is probably more complicated than only doing a very basic 
BFS loader  (though it probably have to be done in assembly, due to the 
lack of 16bit real mode compilers).

I will have a closer look at the multiboot standard before defining the 
protocol between stage 2 and the kernel. If it's not too much work, I 
would try to be compliant, just to not have to change the protocol 
again in the forseeable future.
