I can confirm that adding nox2apic to the boot options fixed the freezes, and brightness adjustment works correctly. Here's my set up for reference:
- ThinkPad W520 - NVidia Quadro 1000M - Intel i7 QM2760 - 32GB DDR3 1600 (PC 12800) - 2x Samsung 830 256GB SSD configured with Linux software RAID0, LVM, and LUKS - 64-bit Ubuntu 12.04 Beta w/binary NVidia drivers One little kernel flag to solve all my problems and everything is working great now.
