can't load agpgart module for XFree86 i810 for i845G/GL controller (Woody, 2.4.18)

[Daniel Barclay <daniel@fgm.com>]

Has anyone gotten an Intel 82845G/GL graphics controller working
with the XFree86 4.3 backport to woody?

Currently, I'm having trouble loading the agpgart module that X
apparently needs.

The X server dies saying:

  (EE) GARTInit: Unabled to open /dev/agpgart (No such device)

(although xf86cfg started X server okay).

Assuming that that message means that I need to load the agpgart
module, I tried "insmod agpgart", but got the error:

  /lib/modules/2.4.18-686/kernel/drivers/char/agp/agpgart.o: init_module: No such device

Does that mean that 2.4.18's agpgart module is too old to recognize the
845G?


Thanks,
Daniel
