There's been some good progress - I sent a few messages to the syslinux 
mailing lists and hpa plans on fixing the GPT MBR in the near future, so we 
have that part of the problem covered. For now, I guess we can just comment 
out the "if" that chooses between mbr.bin or gptmbr.bin so that the USB key 
would be only EFI or only MBR compatible until this is resolved.

The other half of the problem is that recent kernels hang when booting from 
EFI (bug 466954). Peter Jones was able to find out which commit broke EFI 
booting, but we're not sure how to fix it yet.
