flicker with 304.88 and GeForce Go 7400, FreeBSD 9.1

I get an occasional flicker - sometimes two flickers within 20 seconds, then it will go a while without a flicker. I can’t find a pattern to it.

I appreciate any help or hints to diagnosing and/or solving.

My /boot/loader.conf is pretty simple!:


The machine is an 2006 model HP Pavilion dv8000.

Previously, I had Gentoo Linux on this machine, with the same driver version (latest 304 for linux) and had no problems. Also, before that, I had an install of PCBSD 9.1 on the machine, and I had no problems with the driver on that, but I don’t think it was 304.88 (it was pehaps an earlier version of 304, but I can’t confirm that).
