There are actually 2-3 issues in this bug: a) There is the incompatibility between the fglrx and the intel driver. In order to get around that, the workaround for now is to patch the intel driver (reverting a commit) b) The fglrx driver did not included some paths and this prevented applications needing direct rendering from functioning Both fixes are now included in my PPA.
Muxless hybrid systems with fglrx/intel drivers should work by now if they select the dgpu. For issues when using the igpu there is the separate Bug: #1088220 Personally, I have a muxless based on 6630M .
