Steve - After looking at the code and reading the Kconfig blurb I don't think this is a very good idea.
"This is useful for kernel debugging when your machine crashes very early before the console code is initialized. For normal operation it is not recommended because it looks ugly and doesn't cooperate with klogd/syslogd or the X server. You should normally N here, unless you want to debug such a crash. You need usb debug device."
I'd rather not break klogd/syslogd. We could certainly build a test kernel to help you debug the UEFI boot sequence.
