Here is a patch for -current to add AGP support for the Intel i915
video chipset. It's adapted from FreeBSD, with some minor changes.
This allows X.org to run on this chipset with the hardware
accelerated i810(4) driver.
I have tested this patch on my ThinkPad X41 notebook, and everything
seems to work correctly. It should also work for other machines with
this chipset, obviously. Please let me know if it does.
If needed, I can also post a dmesg and a full X.org logfile.
