The reason for this lies in "GPIO magic". With the configuration for card
88, the GPIO configuration for the channel decoder is wrong, so the DSP in
the channel decoder can't boot. But it needs to do this only once after
power up. So we need a specific configuration for your card. The question
is: How do we separate it from the other cards?
By the way: Does your card have a fan?
