I've been doing a little more research and apparently there is a driver (NVdriver), available for linux and XF86 4.x, that provides excellent 3d performance. The downside is that it appears to require a module in the kernel, which, I presume, makes it very linux-specific. But I'm wondering-- will FreeBSD's Linux API handle this sort of thing, even for kernel modules? The other issue-- how hard is it to have two XF86 installs (3.3.6 and 4.1) side by side?
