    Ok, I jujst got a brand new Dell XPS laptop a few days ago. I managed to
    install Windows 7 and SL 6.1 side by side in a dual boot setup.  This
    laptop has the core i7 processor, which means it has integrated Intel HD
    3000 graphics, but it also has a 2GB Nvidia GT540M (with optimus)
    discrete card as well.  I know that optimus is not natively supported
    yet, but according to the SL forums, the generic nvidia driver can be
    installed instead (kmod-nvidia). The instructions said to just do "yum
    install kmod-nvidia".  This installed the drivers for me and when I
    rebooted, I saw the plymouth-rings splash screen for the first time
    ever, but the system hung.  I restarted again and pushed ESC to see the
    messages and the screen flickered a few times and it stopped on
    "registering binary handler for windows applications" Some googling
    info
      rmed me
    that this was due to the wine service being enabled, so I
    disabled it and restarted.  This time, it got hung on "starting atd:"
    and the screen flickered a few times.  I have a feeling that if I
    disabled atd, it would just hang on the next service. I had to uninstall
    the kmod-nvidia package just to boot my system again.  There has to be a
    way to get the nvidia driver working.  Any help would be appreciated.

Some good info over at the archlinux forums:

To test the nvidia driver: blacklist the nouveau and intel graphic modules, disable kernel mode-setting, and boot to runlevel 3 (all via the kernel command line args below). Then run nvidia's xorg creation tool (nvidia-xconfig). Give X a try and see if it works.

nouveau.disable=1 intel.disable=1 nomodeset 3 <--append this to grub kernel line

If that wont work, black list nouveau and nvidia, and try the intel module (delete the xorg.conf made by nvidia-xconfig)

nouveau.disable=1 nomodeset 3 <-- append this to grub kernel line

Hope that helps.
