The problem you describe (switch from and to VC) is being discussed on dri-devel mailing list, and is a known problem since XFree86 4.2.0 (possibly not related to DRI at all). I don't think a solution has been found yet, but some people are looking into it. Reportedly, the only working package that is known to work is some heavily patched package of XFree86 4.1.0 from Debian :-(
