I'm not sure the exact details of your hardware problems but you may want to try out Qubes R4.1 when it's released (or the RC1 version now). It will ship with a fully updated base hypervisor and kernel feature set thus granting support for newer hardware.
Otherwise, feel free to open an issue on the Qubes issue tracker and the Core Team will look into it.
