Well, since AMD took over ATI the support for the open source Linux drivers has improved a lot. However, this generally just means that AMD cards a few years old work pretty well (like the one in the machine I'm typing this from). It would be nice if either the open source or the proprietary drivers would work well on new hardware.
Other file managers worth mentioning are gentoo file manager (no relation to the distribution; it predates it) and xfm, which is very lightweight for a graphical file manager.
