Oops, I meant to reply to the list. Resending: Maybe you could use something like manymouse[1] and interface to it with ctypes? It's a cross-platform C library for low-level mouse input. On Windows it uses raw input[2] which gets raw movement data with no acceleration applied[3]. Of course, you could write directly for the Windows API, but I think manymouse looks a bit easier and will be handy if you want to use other platforms. Using ctypes can be a bit tricky if you're new to it, but this API looks extremely straightforward, so I don't think it should be too painful.
