I got this one. It has also AZT3320 chip.

The JMPCFG was set to software.
I run into these problems:

1. There is a problem with freeing resources in the probe function. If the probe
ends with error, removal of the driver does not release requested regions, so the
driver cannot be reloaded again (and cat /proc/iports crashes). It is easy to
reproduce: give irq number which is already acquired by another driver
then unload driver.

2. After a while I found the free irq (it took quite long with this manual settings).
 The driver loaded, the /proc/asound/* files showed GALAXY something
but the alsamixer ended with message that there was no mixer device. 

I look forward to next version of your driver to test,
