Ofcourse your software would have support. This leaves drivers on FreeBSD. I know for a fact the drivers are getting a little old, but I am not capable of updating them. Here is an example(not that everyfile need to be days old to support what you have): http://www.freebsd.org/cgi/cvsweb.cgi/src/sys/dev/drm/radeon_cp.c ->9 months, 4 weeks ago http://freedesktop.org/cgi-bin/viewcvs.cgi/dri/drm/shared/radeon_cp.c ->10 days, 23 hours ago Thats just half of it. Forget about anything over the R200 core(radeon 8500, the low 9000s are just variations on the R200 and work too) if you can not use the precompiled ati linux drivers. I hate to say it, but go to linux or windows since that is what you need to get yor work done. I recommend Gentoo, its very BSD like.
