...t there are issues, such as that the pv-ops kernel has a different understanding of memory (for details check out: http://wiki.xensource.com/xenwiki/XenPVOPSDRM). I've fleshed out most of them (like GART had the wrong phys addresses, ouch!), but the one that I am stumbling at is that I see the PFIFO_DMA_PUSHER, which I am to understand means: "Oh, the GPU obj operation you stuck on the RAMHT/RAMIN is busted." So first of, is there a register to poke to find out which DMA operation it is talking about ? Or is it pretty fast - so I can surmise that: [ 13.271499] [drm] nouveau 0000:01:00.0: no...

If you're especially unlucky BOs would move around and their kmaps would end up pointing to something else in GART, then ioctl_pushbuf() would use the kmaps again corrupting textures or other pushbufs (the most noticeable symptom was a PFIFO_DMA_PUSHER from time to time).

...LT/IB_EMPTY errors (?related to the actual amount of vram your card has?) and last but not least * you're using an _ancient_ kernel Thus first and foremost I would advice that you experiment with various kernels (older and newer) and (hopefully) you'll find one that does not produce "PFIFO_DMA_PUSHER" style of messages. You can easily check that even without X, just login in VT and look at your dmesg output.
