nForce / ATI Radeon 9800 Pro - linux problems

I’m using an Asus A7N8X Deluxe motherboard with an ATI 9800 Pro (AGP) video card. When I install Blender3d WinXP version everything seems fine, when I install it under Xubuntu menu’s and border select don’t show.

On the downloadspage this is referred to as an Intel driver bug but I can’t find anything related to my situation.

I’m using the (proprietary) ATI accelerated driver for linux and have altered xorg.conf as to support dual monitors, as I also do use in XP.
Installed packages are xorg-driver-fglrx, xserver-xorg-video-ati, radeontool and fglrx-control (=fireglcontrol).

BIOS Version: BK-ATI VER008.004.019
Display Driver Version: 8.34.08
