[Libva] Intel 945GME

[Peter Christy]

Computer: Advent 4214 Netbook (dual core Atom N270)
OS: Slackware current (13.0)
Graphics chipset reported by lspci: 00:02.0 VGA compatible controller: Intel
Corporation Mobile 945GME Express Integrated Graphics Controller (rev 03)

Problem: I have successfully compiled (I think!) and installed libva

However, vainfo reports:
libva: libva version 0.31.0-sds4
libva: va_getDriverName() returns 0
libva: Trying to open /usr/lib/va/drivers/i915_drv_video.so
libva: va_openDriver() returns -1
vaInitialize failed with error code -1 (unknown libva error),exit

1) I thought I had built version sds9!

2) The only drivers in /usr/lib/va/drivers are the dummy and i965_drv_video.so

Questions:

1) Is libva compatible with the Intel 945GME chipset?

2) How do I persuade either libva or X to use the 965 driver instead of the 
915?
(the intel documentation implies the same driver is used for both)

3) Have I missed something? Information on setting up libva is sparse!
