that's exactly the same model as mine (sadly). The install works fine, ZFS is awesome, but I couldn't get the console to cover anything other than ~ 2/3 of the screen, nor get anything at all working under X. So not very functional. I'd be happy with running tmux in a console if 100% of the screen could be used, and if the font FreeBSD is using as EFI boot time would stay on the screen, but it doesn't. Short of donating to the FreeBSD Foundation and waiting a few years I don't see much hope here. Sadly installed linux mint this week to get some work done :-(. A possible alternative *might* be to set up Xen or bhyve, and see if some sort of PCI pass through to a compatible guest is possible, a la
http://lists.xenproject.org/archives/html/xen-users/2013-11/msg00231.html and
https://wiki.freebsd.org/bhyve/pci_passthru which believe has only been used for network devices so far... if a more experienced person would advise whether this is feasible that would be really cool.
