I see a CSM as a pre-requisite for merging a uefi rom.  A user can 
already use a uefi rom by simply using the -bios parameter so there's 
nothing inhibiting testing.  My concern about introducing a new machine 
type is that it would require duplicate testing and force the selection 
of uefi up through the management tool stack.

OTH, uefi + a CSM based on SeaBIOS could be used as the default 
firmware.  I don't think it's a reasonable target for 0.12 but I think 
if someone actively worked on it, it would be possible for future releases.
