which chipset works best with linux/bsd

[newlinuxguy]

hi,

i am planning to buy a a64 system for office

choises are

1. nvidia chipset based
2. via chipset based
3. sis chipset based

which one of those has the best driver support for linux/bsd

i can give up a little on performance/features in return for smooth linux/bsd installation and support. i dont want to spend hours trying to get something work with linux.

thanks
