[gPXE] gPXE license clarifications

[Miller, Shao]

Good day Vagrant,

I sent these out:

http://etherboot.org/pipermail/gpxe-devel/2010-March/000086.html
http://etherboot.org/pipermail/gpxe-devel/2010-March/000085.html

and received zero responses.  I'm not sure why.  I'm not sure why
they've not been committed.  I'm not sure if it helps you out.  It would
be nice to see your Debian efforts come to fruition.
