There is a new driver in HEAD called mps that supports the card. People have had varying amounts of success running the driver ported to 8.x. I can provide you with a .ko that works on 8.x, but it comes with a YMMV warranty. FWIW, this driver won't be appearing in 8.2 due to various concerns the people working on it had with it. -- Thanks, Josh Paetzel [-- Attachment #2 --] -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.15 (FreeBSD) iQEcBAABAgAGBQJNQCvBAAoJEKFq1/n1feG2oHQH/0uAiwZBywRJOdzzc9lFckva uXuPMemjl4/AXLRagwiSrmXfbwv64I61jGAAbpT2YjV/WFgAVTIPCuEjjo22sw8K VoXks9kodonfyFsvFjqy1YB88IN8NfCR95aU4rT8CAozfgg2L/mJ0RAce9nAMNAU aarp1zC4Fhbxd3T22eYdswhoDD7O02JlqUti2zAiJu/Hydm3v5ATi8eiXRWrx9iK 3Rk+b4BbQ5S67oI1iFpQp+4AtTbTEFKr1c31JPyr5IwCqd9d41tewbXuzMHPMITU AhdMnlrsJaj4yDLLGuxsHfV07gYRFi1dSCc9Cg6gpdTrm8d77/OPZH30fAclp48= =j3q/ -----END PGP SIGNATURE-----help
