[PATCH] x86_64: Add option to disable timer check
This works around the too fast timer seen on some ATI boards.
I don't feel confident enough about it yet to enable it by default, but give
users the option.
Patch and debugging from Christopher Allen Wing <wingc@engin.umich.edu>, with
minor tweaks (renamed the option and documented it)
