I'm not totally against these patches, but these cards really aren't meant = to be run with the ACR firmware these days. You're going to hit pretty regular issues and bitrot pretty regularly if we don't just figure out why exactly it's not loading - could you send a dmesg from when your system boots up so= we could take a look?
