Question Various xorg display drivers and CUDA?

I just dropped by to ask a quick question on which I didn't want to spend too much time googling around or reading docs.

I happen to use CUDA quite a bit (work-related and such) on my nvidia cards (9800GT on desktop, 9800M GS on notebook). The question is that can I use a different xorg driver than "nvidia" to drive my display (something like "vesa", "nv" or "nouveau") and yet load up the nvidia.ko kernel module and happily use CUDA too? I do know that CUDA does work (and works better) without X running. While I can easily test out "vesa" or "nv" sometime, my question is mainly about "nouveau".

Also, to clarify, the drivers from nvidia are awesome and feature-wise complete to my liking . Just that I got an itch to know more about nouveau and possibly try it. The pros I think would be possibly a lighter and more basic driver and tightly integrated to kernel (kms cough cough) and xorg, and possibly better multi-display management. Currently, while the nvidia-settings app is good for managing twinview, I am a bit vexed with this one large display resolution and things getting centered and/or stretched, rather than two connected desktops with different resolutions. (Yes I can do xorg.conf, but doing things often on notebook is tedious.) Besides, if I can get more resources for CUDA, it would be awesome. But the big cons I can see with nouveau is power-management (does it work to some extent? acpi?) and video acceleration (I use it often and love it) and overall desktop experience (I hate graphical glitches).
