The -i810 driver is the old one replaced by -intel. Since it doesn't seem to be a hardware issue because it works fine with -i810 driver I guess the best option is to report it upstream and post the link here. There is a HowTo for Intel driver bug reporting. http://intellinuxgraphics.org/how_to_report_bug.html . If you have questions just ask.
