I've run ps2.exe on the ThinkPad and all the settings it lists for the audio 
are the same in your modprobe.conf.  However, there are a few settings in 
the conf that ps2.exe didn't give:
index=0: I take it this has nothing to do w/the sound board settings...
id=CARD_0: nor this.
port=0x530: same
cport=0x538: There's an "ADDress   : 538" in the AUDIOCTRL settings
sb_port=0x220: same
fm_port=0x388: ps2.exe doesn't show this
irq=5: same
dma1=1 and dma2=0: ps2.exe had "DMA   : 0 1". does order matter?
mpu_port=0x330: There's an "ADDress   : 330" in the MIDIport settings
mpu_irq=9: There's an "IRQ    : 9" in the MIDIport settings
The MIDIport settings also have "Disabled"

But I feel that this has more to do with the driver and chipset. The error I 
get on startup from insmod is that there is no such device. I guess I don't 
blame it for thinking that since lspci also seems to think there's a 
different model in there.
