There's a problem with the i830 driver in XFree86 4.2.x, which makes it think you only have 1 MB of video RAM. There is a patch which fixes this problem. It'd be nice to have this included in the ebuild, so you don't have to do it by hand. The problem has been fixed in the XFree86 CVS tree, and should be included in XFree86 4.3.0. Description of the bug: http://www.cse.unsw.edu.au/~chak/linux/c400.html#xfree86 Patch: http://www.cse.unsw.edu.au/~chak/linux/i830_driver-1mb-stolen-hack.patch Info on the rewritten driver for X 4.3.0:http://www.xfree86.org/~dawes/845driver.html
Added to xfree-4.2.1-r2, please test when out.
Fixed.
