Nvidia efore 6600 uses the older legacy driver 87.?? , the one running now is default 100.?? and this might be the cause of your bugs.
The guys with the nvidia 8800gts or better will post later and the specific brands they have.
Also check gentoo.org forums / wiki's and our own wiki on top of this page for more info on brands.
Edit : Do not be fooled by Ati or Nvidia as they have the default video cards = *800 models like 6800 / 7800 / 8800 and all others is cloned + underclocked / overclocked versions of this be it in the bios or using hardware resistors. Look at the 8700m laptop video card brand new and a bit better power saving = wow , my junker 7800gtx in my laptop running at 50% power / underclocked can still nuke the 8700m even if 8700m is overclocked.
