F17 video annoyances, old hardware

[stan]

F17 boots using nouveau for my old Nvidia hardware (MX420).  There are
two problems with this for me.
- nouveau doesn't allow different resolutions on consoles and gui.
- mplayer can't adjust brightness and contrast.  This is strange
  since qiv can.

On F15 I'm running the old nv driver to get around these issues, and it
works fine.  However, when I try to use it in F17, with an xorg.conf
file, it gives the following error, and refuses to start.

I can't find this module xaa.  Can anyone tell me where it is?

Thanks.
