A debugged version of the driver for Intel740-based graphics cards taken from http://sourceforge.net/projects/i740fb/ that supports XVideo and DGA. Patrick Lerda did all the hard work - I just fixed a bug or two (It was unreliable on my system.)
For my bug fix version, which includes a binary for Linux/i386,
For Patrick Lerda's original,
Note: I have discovered that XFree86 4.2.0 is a lot more reliable than 4.1.0. The session would spontaneously die in 4.1.0, and Xine would exacerbate it. This driver can be built for 4.2.0. The patch works, but you have to correct a few merging problems, since it was made for 4.1.0. I will release it properly for 4.2.0 with a binary some time or other. (Feel free to bug me.)
This code has been integrated into the XFree86 4.3.0 codebase, so if you are using 4.3.0 or higher, you shouldn't need to download anything here.
