Interesting.  I tested KVM and don't get double characters.

Also not a problem I see here.  This may be dependent on the KVM version.

I have noticed that the BIOS console has been noticeably slower since 
upgrading QEMU/KVM a couple of months ago.  I'm pretty sure this isn't 
an iPXE-specific problem, since the BIOS's own startup banner also 
prints with a noticeable teletype effect.
