Well, the OS needs ACPI, but I'm defnitiely not going to parse a DSDT
in SeaBIOS.

I'm not that familiar with them.  My preference would be something
very simple, like key/value pairs.  I don't object to a heirarchical
storage if it's simple though.

That's a good question.  I don't have a reliable way of measuring
times.  I don't perceive a slowdown, but it's hard to tell because
epia-cn is a bit quirky right now -- coreboot seems to reboot like
three or four times before launching SeaBIOS.
