Hi,

I do not quite understand how DDB_FROMCONSOLE works.
ddb manpage states that key used to activate DDB from
console can be changed from default on i386 ctrl-alt-esc to
any string in hw.cnmagic.

But if I set sysctl -w hw.cnmagic="string" then ddb remains
activated by ctrl-alt-esc.  What do I do wrong?
