I did a few additional tests and there seems to be only an issue with brandnew cards which have never before got a firmware uploaded. As on my card register 0x20 allways returned 0 with different kernel and driver versions and several reboots. After forcing a firmware upload by modifying the driver to not check the state of register 0x20, the issue no longer exists. If I now reboot or power cycle the PC, register 0x20 returns values unequal 0 and the original driver works as expected. It seems to me that relying on register 0x20 for firmware uploads is not stable as a brandnew card may return 0 until it got the first firmware uploaded.
