Real Hardware Errors :/

Ok, so I am having (a lot) of trouble getting UHCI working on real
hardware..

* Device gives time-out on my transaction even after a successful
reset/enable
* Fixed spinlocks in the whole system and thus fixing some hang-up
issues (the fuck was i thinking).
* Fixed some issues relating to the virtual memory system
* There is an issue with the scheduler that seems to almost lock-up a
thread completely, the fuck is happening
