I've just noticed that.  I think x86_64 should default to "i386-pc"
platform.  I'll have a look how to do it nicely.

I was trying add an extra check there, but ran into more interesting
stuff.  Basically, the target checks should be better separated from the
rest.  I'll take another look.

I didn't know grub-emu could load modules!  Live and learn :-)

Perhaps we'll have it eventually.  But I agree, the default should be
restored for now.
