Ok, I will read this. Still I want to have first something that works.
Creating or not a new port will be only a matter of time.

Yeah, I already started sending messages there. Maybe I should also talk
about this in one of the tech mailing lists.

I am still working on the bootloader. It would be nice if someone can
help me out on this, since I don't have too much experience on this kind
of issues. And by the way, Linux also uses ELF kernels.

I enabled USB ethernet on my kernel+ramdisk. Once I buy one of those, I
will configure the ramdisk to assign an IP to the USB nic.

The console issue is one of the last ones for me. I will be happy enough
with a remote console through ssh. Once I get that, I can work on porting
the nvidia drivers from Linux.

I didn't start looking at that, yet. But since Linux has all the tools for
this, I don't think it will be TOO complicated.

It will be easier just to use NFS, what do you think?

Yeah, but all this goes to the bottom of the stack.

I already started with those... :-)
