Hmm.  Perhaps.  The SGI Itanium nodes start their memory at 196GB.

For commodity stuff standardization is the rule of the game, so
how much of this we will have to deal with LinuxBIOS wise is an interesting
question.  Mostly on the embedded stuff I would suspect.

No, I have just been talking to a lot of people doing embedded stuff.
And I like to look at problems long before I actually have to cope with
them.

ARM kernels currently have a fair amount of board specific knowledge
in them.  An ARM BIOS is so far to easy to share code with LinuxBIOS,
but we may be able to share a table structure with.
