Oh, I forgot, there was a bad v86 info thing on the 9th cpu woken
that I never finished debugging, too. And the MAX_IO_APICS issue,
which is easily solved by just increasing the constant #ifdef
CONFIG_MULTIQUAD as usual. This panics before console_init() though,
which makes it seem more painful than it really is.
