Hi Otavio:
Thank you for your quickly response. 
We are glad to do a grub2 patch. However, it will take us some time. We have not touch grub2 before, and our moblin stack uses grub-0.97 in these days, and we can not spend much effort on it. 
Any way, we are very interesting in the work. If we have resource, we can continue to work on the grub-2 patch.

I personally loves this new idea and agree with the approach however
GRUB 0.97 is at legacy mode (on upstream side) and it makes rather
difficult to us (Debian) to keep using it.

We're focusing our efforts in moving to GRUB2 and I'd like to ask if
you could work on a patch for GRUB2 too? It would allow it to get
accepted upstream and removing the maintainence work (in theory at
least) from you.

BTW, is the patch very intrusive?
