[PATCH -mm] console: console_drivers not initialized

[dwalker@mvista.com]

I was doing -rt stuff on a PPC PowerBook G4. It would always reboot
itself when it hit console_init() .

I noticed that the console code seems to want console_drivers = NULL,
but it never actually sets it that way. Once I added this, the reboot 
issue was gone..
