Running Squeeze on my wife's laptop gives horrible graphics performance

The currently-installed Ubuntu 8.04 works fine. Lenny on a live usb
works fine. Squeeze and Ubuntu 10.04 on live usb both show similar
problems with the graphics.
Some preliminary research suggested that booting with "nomodeset" might
fix it. It made a difference, but didn't fix the problem. On Ubuntu
10.04, "nomodeset" fixed the display problems on the bootsplash, but not
on GDM or the logged-in desktop. On Squeeze no difference was noted,
but it doesn't use a boot splash.
Have you tried the nVidia binary driver/kernel? I have used the same graphics card (less the Ti) in a Latitude D800 running Lenny without the nVidia driver and it worked okay, for what it's worth.
