Not for the oddball case Haavard mentioned, no:  the console port
being something the boot loader wasn't using, which couldn't show
the early boot messages (before console setup) in any case.  Those
kinds of systems aren't especially debuggable (it's JTAG or nothing).

I don't have any issue with getting that fixed too ... but unless
someone has a platform that relies on that case (or can be made to
do so, for testing), then it's hard for me to worry about it!
