It can also be set at boot time. It defaults to 1 now since it can be set in the boot loader. If this proves unwise, we can reset it to defaulting to 0. If enough people have trouble with this default, we might want to set it to 0, since 1) We can't please everyone. 2) We should try to please people with working hardware first. Ciao, Sheldon.
