>happily running my broadwell laptop

That's interesting. On my Cherry View dev board which is also Broadwell
graphics (I think) I get some output from kldload i915kms but then it
halts. USB keyboard still works (as in I can press enter and console
scrolls up) but no response from OS.

I do get some message about bus_register something missing..

Maybe not ready for testing?
