Sorry, I can't find any specs for a CQ62 with both ATI and NVidia. 
There's a trademark name for the dual GPU systems, at least the 
Intel-plus-something-else kind, but I can't recall it.

The start of /var/log/Xorg.0.log would be interesting, both for the 
version of FreeBSD and the version of xorg-server.  I don't think I 
have anything with dual PCIe X16 slots to test.

Usually it's finding someone able to do the work that's willing to do 
the work.  The Foundation is funding some of that, and I've heard 
they're interested in getting the KMS for the Radeon driver going.
