dmesg of regular boot + startx

Trying to run Arch Linux on a Lenovo Y400 with an nvidia GT750M graphics card.
When trying to boot the nouveau drivers consistently spit out multiple errors.
Computer continues the boot process. Errors also occur whenever I try to run
anything with hardware acceleration, such as Xorg. It is a similar output to
the one that occurs during boot: PBUS, PIBUS, and PGRAPH errors. Attached is a
dmesg log of a regular boot and startx.

Also a log of opening up Xorg: http://pastebin.com/w48Dx4qq
And a log of opening up weston: http://pastebin.com/1VPFgapP
