The joke is, that this behaviour is caused by a mistake. Here is the right
patch against current CVS:
Index: emumixer.c

change = (reg & HCFG_GPOUT0) != val;
At least, we know that for rev07 cards we shouldn't modify GPOUT0. These
cards have separated the digital output or shared with an analog output?
