Come on, are you serious about this? The man page of inteldrm(4) has a section intel(4) where you can see the supported hardware very nice listed. It is super-giga-quite obvious that what is not listed there is not supported. Suggestions like yours are making other's people lifes more difficult at work, in a sense that a final product is filled up with warnings and attention bells. And redundant procedures. And super-redundant procedures ... Since you have already bought that hardware, do email the manufacturer for documentation. There are 99% chances that you will get nothing, but your email will increase the awareness for open source users, maybe.
