Just got around to giving this a spin again and unfortunately the preffered 
options code isn't working for me:

rene at 5bt1:~$ cat /sys/bus/pnp/devices/02\:01/options
Dependent: 01 - Priority preferred
    port 0x220-0x220, align 0x0, size 0x10, 10-bit address decoding
    port 0x330-0x330, align 0x0, size 0x2, 10-bit address decoding
    port 0x388-0x388, align 0x0, size 0x4, 10-bit address decoding
    irq 5 High-Edge
    irq 2/9 High-Edge
    dma 1 8-bit compatible
Dependent: 02 - Priority acceptable
    port 0x210-0x260, align 0xf, size 0x10, 10-bit address decoding
    port 0x300-0x330, align 0xf, size 0x2, 10-bit address decoding
    port 0x388-0x388, align 0x0, size 0x4, 10-bit address decoding
    irq 3,5,7,2/9,10,15 High-Edge
    irq 3,5,7,2/9,10,15 High-Edge
    dma 1,3,5,7 8-bit&16-bit compatible
Dependent: 03 - Priority acceptable
    port 0x210-0x260, align 0xf, size 0x10, 10-bit address decoding
    port 0x300-0x330, align 0xf, size 0x2, 10-bit address decoding
    port 0x388-0x388, align 0x0, size 0x4, 10-bit address decoding
    irq 3,5,7,2/9,10,15 High-Edge
    dma 1,3,5,7 8-bit&16-bit compatible
rene at 5bt1:~$ cat /sys/bus/pnp/devices/02\:01/resources
state = disabled
rene at 5bt1:~$ su -c "modprobe snd-jazz16"
rene at 5bt1:~$ cat /sys/bus/pnp/devices/02\:01/resources
state = active
io 0x210-0x21f
io 0x300-0x301
io 0x388-0x38b
irq 5
irq 7
dma 1

Ports 210 and 300 are first from the acceptables, not the preferreds and the 
irq 7 is also not preffered for MPU. Yes, ports 220, 330 and irq 9 are free.

Looking back through what I sent earlier, I see I sent you a wrong patch 
then so I'm not sure anymore what I tested and I don't have time to look at 
it now. Thought I'd let you know though.

Rene.
