I mean the error messages from my original report.  They say "make sure 
your kernel is using the agpgart module", when in fact the kernel is 
using this module and the problem is that's not enough.  A better 
message might be something like "make sure your kernel is using the 
agpgart module.  Under kernel 2.6 and higher, you'll need to use a 
chipset-specific AGP module as well."  This would have been sufficient 
for me to find and fix the problem on my own.

I figured this one out: I needed to modprobe the psmouse kernel module. 
 Apparently this is another linux-2.6 change.  But since this module 
wasn't available, X would start normally and the mouse just wouldn't 
work.  I'm not sure what X can really do about this.

If you need more, I can get you a full log with either of the above 
problems.  But I'll have to reconfigure my system to be broken again to 
do it...
