Help obtaining kernel module for video driver [savage.ko]

[Brandon Kuczenski <brandon@301south.net>]

I am running debian-testing on linux 2.6.8 on an IBM T23 laptop.  This 
system has been running for about 2 years.  I recently upgraded XFree86 to 
Xorg (running 7.0.0) and now my video card direct rendering has stopped 
working.  I extracted the following lines from my Xorg logfile:

...
drmOpenDevice: Open failed
[drm] failed to load kernel module "savage"
(II) SAVAGE(0): [drm] drmOpen failed
(EE) SAVAGE(0): [drm] DRIScreenInit failed.  Disabling DRI.
(EE) SAVAGE(0): DRI isn't enabled
...

I searched the computer and savage.ko is nowhere to be found.  What's the 
best way to obtain this module under debian?  I have a full kernel source 
tree on the machine, but I don't know if it's part of the kernel source or 
somewhere in X or what... I would be happy with a pointer to some good 
documentation.. the stuff available on the dri.freedesktop.org wiki is not 
very clear.

Thanks in advance,
Brandon
