For those of us who find older hardware quite adequate for our purposes, I offer this post with the solution that I found and I am also seeking an explanation of why it works.
My Deskpro EN successfully ran X under FreeBSD 7.x. When I loaded FreeBSD 8.0-RELEASE, X ran but with a garbled screen. In both cases the video driver was xf86-video-intel-2.7.1_4, but compiled under the relevant operating system version.
Thinking this may be a memory configuration issue, I tried modifing i810_memory.c. When I commented out the section that adds in the Dcache memory and compiled the driver, I had a working X. The the file diff below.
I have not pursued the matter any further, but I would appreciate any comments about what is causing this behaviour.
Enjoy!
