I have the exact same problem, with a different laptop, but the same chipset. My physical address is the same though my IRQ is 10 for both video and audio. But I find it curious your video and audio do not share the same IQ since they are the same chip.
I studied the source for the NM256 ALSA driver. As best as I can tell is the problem lies in the config for the AC97 codec driver. I havent dived into that yet, so I am not sure. I could probably submit an update, if I had specs, a better understanding of the hardware, and/or someone to help.;P If you ever hear anything off of the list, please let me know, as I am interested in using the ALSA sound driver too!
