thanks for the tip..
Here's my result:
Since the install set does not support this video card correctly, it was necessary to use the "text install" method to install without using the GUI. Installing the latest and greatest Nvidia drivers did not help to get you into the KDE though.
After numerous attemps, it turns out that the "vesa" driver worked perfectly. I just had to edit /etc/X11/xorg.conf and replace "nvidia" with "vesa" and I was good to go. The other thing I have to get working before I can install LinuxMCE is to get the system to recognize my onboard NIC and sound.
I will update this thread with my findings so others with the ASUS M3N78-VM board can benefit.
