But it's not a tunable and I was hoping to not have to pull gpxe into 
the tree and start adding patches.

Maybe we could wait until 0.13 and then introduce the FW cfg interface 
to gpxe?  I've already talked to some of the gpxe devs about it and they 
seem pretty receptive.  That would let us define how long the timeout was.

The advantage of leaving in the timeout is that it lets a user access 
the gPXE menu even if it's not set to be bootable.  You see this on bare 
metal all of the time with gPXE.
