More D830 HW support in Solaris
Looks like CR 6580728 "Upgrade Xorg Intel video driver to xf86-video-intel-2.1.0" has brought support for the full resolution of my display on the D830. I should try it ;)
I also received word from Simon-Bernard Drolet that the latest release of the OSS (v4.0-1006) produces sound from the line-out jack, though not from the speakers. We are discussing this issue in the 4front forums.
