It's already in there in fact. It wasn't originally, until we discovered
that there is no way to output a message in head.S when you're
using vesafb. The only way to give a visible error is to do it
before the video switched.
The old test was kept, although it's redundant.
This means Vivek/Eric added it now to the SMP trampoline and ACPI
S3 resume too, but there it is technically redundant too.
But you have to spin, otherwise the user cannot see what is wrong
(and that is much more important than your obscure possibility
of automatic fallback -- inserting the wrong CD is pretty common)
Finding panic=.. would require writing a command line parser in 16bit assembly.
I have my doubts that's a good use of anyone's time.
