- mesa-7.1-fix-i8xx-vbos.patch
* For some reason the Intel 865 seem to claim VBO support in the
docs, but doesn't seem to practice it in the hardware, or
there is some missing errata. This restores the old pre-vbo
code and uses it on all 8xx hw. (bfo #17963)
This patch fixes OpenGL support on 845/855GM/865.

Subject: [PATCH] intel: restore old vertex submit paths for i8xx hardware.
For some reason the Intel 865 seem to claim VBO support in the docs, but
doesn't seem to practice it in the hardware, or there is some missing
errata.
This restores the old pre-vbo code and uses it on all 8xx hw.
