[PATCH] Fix Linux/x86 load without virtual-mode -- take 2

[Torsten Duwe]

> I'll have to see yet what's wrong with earlyprintk.

Linux fixups didn't get called because there was no way the Linux ELF kernel 
could be recognised as such. So the fix to the fix is a one-liner plus a 
comment. The recogniser needs further refinement, but on top of LinuxBIOSv2 
this boots Linux at least in qemu and on my real machine.

Please apply!
