xorg-x11 6.7.0 (formerly XFree)
Graphics are driven by the Intel 852GM chipset which doesn't have its own RAM, instead it "steals" 16Mb from the main RAM, so you actually have 240Mb of RAM. One essential thing you'll want is DRI support for graphics acceleration, which requires some kernel stuff as well as the right lines in my xorg.conf (formerly XF86Config). Presently xorg-x11 6.7.0 is pretty much the same as XFree 4.4, so if you still use that you can rename the file to XF86Config or XF86Config-4 depending on your setup.
