Use "lspci -v" to find out whether you have an i810. I have i810, and I have never gotten direct rendering to work. I believe my problem is a mismatch between versions of the drm driver in the kernel and in X Windows, which mismatch has persisted though three kernels (2.5.8, 2.5.66, 2.6.1) and three versions of X (4.2.0, 4.3.0, 4.4.0 snapshot).
On my last try, a couple weeks ago, I installed an X 4.4.0 snapshot binary from Dec. 19, which came with source for a kernel drm module, presumably matching the X driver. But when I stuck it in the 2.6.1 source, it wouldn't compile. Lots of errors.
So, good luck, but I wouldn't be very hopeful of success.
