| |
As far as I can understand from Dave Jone's 2.5.69-dj1 patch in <http://www.kernel.org/pub/linux/kernel/people/davej/patches/2.5/2.5.69/>, Matt Tolentino's AGPGART patch for Intel 875P patch support simply binds the i845 driver in the presence of the Intel 875P PCI ID.
The patch attached does the same thing for kernel 2.4.22. No attempt to verify this from the 845G/875P specifications was made, since 3D acceleration in my machine has been working faultlessly with it.
