A... what?

Series looks reasonable to me.  The one thing that makes me nervous is 
4/11 mentioning the BIOS, which honestly seems like an insane thing to 
let your BIOS have _any_ say in, but then Intel sure does like to give 
the BIOS a chance to make the OS less functional.  The code in 7/11 
effectively limits things to between 4k and 1M; does that actually make 
sense?  I can't imagine wanting to allocate only 4k if it turns out we'd 
always need at least (say) 32k.

I have admittedly not read any of the docs on how this is meant to work, 
apologies if that'd answer this.
