lifetime of linux-supported cards
Our lab has several linux development systems using display cards based on the GeForce 2 MX400 chipset. Earlier this year nVidia dropped support for these cards, thus to use them I need to install the legacy drivers. It is a pain when kernel updates are available a couple times a month; besides I prefer to use the latest drivers. So I think I will be replacing these old boards.
The question is what chipsets are nearing the end of their life cycle? I'd hate to buy a few currently-supported cards just to have them become legacy products early next year. I don't really require higher performance, and I certainly don't need whistles and bells like TV. Simple is better.
Any suggestions on which chipsets might be good choices? Any idea where I can get chipset life time info from nVidia?
