Description of problem:
anaconda doesn't put "VideoRam" line in 'Section "Device"' in file
/etc/X11/XF86Config-4. (It does for /tmp/XF86Config.test and
This is a problem for me, because I use 8MB Matrox Millennium II cards, for
which XFree86 is unable to probe the video RAM size due to a hardware bug and
defaults to 4MB. Even
though I specify 8MB, if the setting doesn't get saved into the configuration
file, I am unable to use the higher-resolution modes with this card unless I
manually edit the configuration file, which many users wouldn't know to do.
Xconfigurator has a similar issue, and I'll log a defect against it too.

Steps to Reproduce:
1. Install on a machine with an 8MB Matrox Millennium video card.
2. Specify 8MB video RAM and a video mode that requires that much RAM, such as
Actual Results: XFree86 4.x refuses to do a mode higher than 1152x864x24,
because it assumes 4MB of video RAM unless told otherwise.
Expected Results: If XFree86 4.x had been told that there was 8MB video RAM,
then it would have used the higher-resolution mode that I selected, such as
This is because the general case is that setting the video ram explicitly for
XFree 4 is the wrong thing to do and there's no real way to know what the few
exceptions are that need it written out.
