That is really nice! Can you get the GRUB menu to work, etc?
How about module loading? I noticed you wrote some code for that
I noticed you used a lot of assembler. Isn't it possible to minimize
the use of assembler somehow? If that is not possible, no problem.

I remember a discussion about this... I noticed you implemented some
disk access code. Is it possible to access GNU/Linux partitions?
Is it possible to write support for the filesystem used on RISC OS? I
can help you with that, if you want that.

Nice. Can you please split up the patch somehow? And please make
sure you follow the GCS. That is an important requirement for patches
for GRUB. If you can do that, it will be easier for me to proof read
the patch(es) before it can be applied.

Perhaps it will be easier if there is one file that defines the
available keys. Now it is arch dependent. Anyway, I remember there
is some room for improvement...

Don't worry about cross filesystem symlinks.

Attaching modules to the kernel?
