^^^^^^^^^^^^^^^^^^^ Then why does it (presumably) prevent
people from using there equipment . Otherwise there is no
point in making alot of noise over a simple message .
I still beleive that a manually setable value s/b available,

Spewing a message about it is OK .

hardware geeks . Not everyone in the world knows kernel level
hacking & not everyone who is a kernel hacker knows -every-
idiosyncracy of hardware .
