You're right, currently the new dde_linux/lx_kit was developed for
ARM64 only. Nevertheless, beginning from today we start to update our
x86 driver base including framebuffer, usb host and wifi driver to use
the new approach, and concurrently update the Linux kernel source to a
recent version.
We are confident to have first working results at the end of March.
Then when an updated version of the Intel WiFi driver is running
successfully that is using the new dde_linux/lx_kit, it might be a good
time to step in and port the Atheros card.

Best regards
