Doesn't work with nVidia Geforce 6150

I've had trouble with all past MEPIS systems on my year-old computer that uses an nVidia Geforce 6150 integrated video northbridge. (Specifically, it's a Foxconn/Winfast 6150K8MA-EKRS.) In 3.4.3 and 6.0, the Ethernet didn't work, which was quite the show-stopper. In 6.5-b5, Ethernet works. So does sound. Both of those are common trouble spots for distros using 2.6.15. But the video doesn't. When I boot the live CD the default way, it gets to the point where it starts Xorg. The monitor goes black and in a few seconds goes to power save mode. Only the red button saves the system. VESA works (which is how I know the Ethernet works) but of course it's unbearably slow.

There's a boot option for the "nvidia" driver, but that seems to not be there. The "nv" driver is what comes up by default and fails.
