Default Re: nv driver with HP 30" not getting 2560x1600 - only 1280x800

The problem is not that the pixel clock cannot be programmed for the high-resolution mode, it's that various other clocks, including the memory clock, start out too low to support high-resolution modes (i.e. the memory bandwidth is insufficient, etc.). The code to update the PLLs/muxes/etc. for all clock domains involved is highly complex.

One option that might work as a workaround is to initialize the GPU using the NVIDIA kernel module (e.g. via `modprobe nvidia; mknod /dev/nvidia0 c 195 0; cat /dev/nvidia0`) and then using the nv driver to drive the GPU.
