Subject[PATCH] modify console_loglevel from commandline
These little patches (against 2.0.35 and 2.1.128, but should apply 
cleanly towards later) allow changing the default console_loglevel with
kernel parameters. These should be simple enough to include in the
current 2.0 and 2.1 trees without disturbing anything.

Two new parameters are added, "quiet" which sets console_loglevel to 1,
and "loglevel=integer" which sets the console_loglevel to some integer
from 1 to 10. This lets me quiet down the boot process of my
distribution (as to not scare anyone) without having to patch the kernel,
and additionally allows me to change it from LILO without including
another entire kernel image.
