This option enables special console drivers which allow the kernel
to print messages very early in the bootup process.
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 on some machines ugly and
oesn't cooperate with an X server. You should normally N here,
unless you want to debug such a crash.
