Just FYI, with kernel version 5.9 and 5.10, I have been unable to
get WiFi on RPi4B 8GB working with 2.4GHz.
5GHz works fine without vc4.ko and fails with vc4.ko.
2.4GHz WiFi is usable with Raspbian kernel 64-bit 5.10,
so I am assuming my hardware is OK.
Since I do not use 2.4GHz WiFi because it gets interfered by my
microwave oven, I have not spent much time on investigating the cause...

Best regards, Ryutaroh
