It is saying that the agpgart kernel module is not loaded.
The i810 driver *does not work* without the agpgart module
(the chip needs to access system memory for the framebuffer).
Check in /proc/modules that agpgart is loaded.
I have
alias char-major-10-175 agpgart
in /etc/modules.conf (you may need to run depmod for the changes to take
effect) to ensure that the kernel loads the module when XFree86 tries to
access /dev/agpgart
Don't bother trying DRI with XFree86 4.3 and a 2.2.x kernel,
i810.o wont compile.
