i migrated from xfree and actually everything runs fine.
distro: gentoo
desktop: gnome 2.6
driver: i810
dri: enabled

nevertheless i noticed a pretty annoying problem. when i startx and switch to a
console (ctrl+alt+fx) and then back to the desktop i see nothing but a black
screen. the computers locked then. no mouse, no console switching no
ctrl+alt+backsp. the Xorg.0.log states the following:

Fatal server error:
EnterVT failed for screen 0
