Black graphics, odd flickering random objects

There's definitely no updated drivers from Sony--that was my first stop.

Any tips on using the mobility modder? I tried the hardware heaven forums and got nothing.

When I try to install the driver directly from Nvidia, I get a message that the install cannot proceed. When I use the mobility modder, I get past that message and the install proceeds, but then only lasts a couple of seconds before saying "install failed"
