Lenovo grew unhappy with MediaTek as well and started soldering down Qualcomm chips for WLAN on their AMD platforms only to be burned by buggy firmware/driver interactions on Linux (which they officially sell and support). And Qualcomm stretches themselves rather thin on the mainline kernel side once a chipset generation is no longer the latest. It takes a tremendous amount of vendor pressure to make Qualcomm do anything these days.
