Cool. Now we're getting somewhere...

Hmm. What irq was allocated to the pcic device when you got this?
You /could/ try redefining the available IRQ's in /etc/pccard.conf
(copy'n'paste from the /etc/defaults/pccard.conf, then edit/trim to
suit). Bounce pccardd and try it out..
You should probably also remove '5' as an interrupt from that list (as
your sound card wants it, and they can't generally be persuaded
otherwise), as well as anything else being used by "standard" devices,
e.g. 3 (if you really want to use the second built-in serial device,
sio1, you have configured), and 12 (if you want to use a PS/2 mouse),
and 7 (if you want to use the parallel port).
Mine has a line like this (dunno if it's empirically correct but it
works for my laptop with flash disks, wi cards, PCCARD modems, NICs and
modular 2nd HDD/DVDs etc - all in addition to the built-in devices):
irq 3 10 11 15
Main reason I trimmed it IIRC, was that my New Media LiveWire would
simply refuse to work on a lot of IRQ's that were apparently valid for
it... The list above constitutes AFAIK, the only IRQ's the damn thing
would work on. However, I don't use it much anymore, as my present
laptop (which inherited the disk & hence a lot of configuration
files/settings) has a built-in mini-PCI NIC/modem.

You're not alone...

Naw, he loves it, that's why he keeps messing with it ;-) *waves*
I think that you'll need to bludgeon the 'wi' device onto an interrupt
it can use, whilst keeping the rest of the system in a state that will
work.
I really think that Warner is the best person to comment here, it's
entirely possible that there's some combination of sysctl settings
that'll allow it to work.
I'm not too familar with your machine, there may even be a BIOS option
that has some affect on IRQ allocation.
However, I started guessing some time ago.. :-)

Yup, that's correct. The full complement of audio devices is:

As you can see, there's no device node for 'pcm' itself - I think
because you only interact with the audio device from user space via the
defined interfaces (mixer, audio, dsp etc.).
Kinda like how ethernet devices don't have nodes in '/dev' either -
because you can only send/receive packets via the TCP/IP stack (which
you can't reach from userland itself), thus there's no need for a device
node.
