Comment 4 for bug 114258

I'm seeing the same thing on gutsy. gnome-system-monitor shows 3.2GB of ram, while I have 4GB installed. I have the latest bios available and it has no option to turn on a memory gap. this is on an asus m2a-vm hdmi (http://www.asus.com/products.aspx?l1=3&l2=101&l3=496&l4=0&model=1585&modelmenu=1) with an athlon 64 x2 5200+
