The kernel configuration (at least menuconfig, which I use) has 

| Device Drivers  --->  Character devices  ---> 
| <*> Direct Rendering Manager
|   <M>Intel 830M, 845G, 852GM, 855GM, 865G
|     <M>   i830 driver                                            
|     <M>   i915 driver

If you can't tell for formatting, i[0-9]{3} are in the category `Intel
830M..."  I had originally compiled them in, and you can only include
one or the other in the kernel.  I had chosen the i830. It was the wrong
choice -- an easy mistake, considering both list the 845G as supported
and the 830 happens to be first. 
	I recommend, if you haven't yet, compiling the kernel with the
Intel drm drivers as modules.  X will load the right one.  In
retrospect, the kernel help messege told me how.
	For what it's worth, you'll also have to have in xorg.conf:

| Section "Module"
|         Load  "glx"
|        Load  "dri"
| 	...
| EndSection
| 
| Section "DRI"
|	Mode    0666
| EndSection

And now the third line of glxinfo should show 'Yes'
| dan@pascal ~ $ glxinfo | grep direct
| direct rendering: Yes
and your glxgears will be nice and smooth, and, in my case, 67%
faster.  

Good luck.
