The problems discussed didn't really relate to the video card, but rather the TV. That video card actually runs very well in Linux.
The only video card issue is that was discussed is a universal problem. Currently LMCE hardcodes which DVI port to use and has hardcoded modelines that don't work with all TVs. I have to put in a manually created modeline for my TV (the TV won't report the correct timings, either). For my other TV I must turn on EDID (actually on by default, but LMCE disables it) and remove the LMCE modeline.
FYI, if LMCE didn't hardcode which DVI port to use in Xorg.conf, Xorg and the nVidia drivers would select whichever port was currently active.
