Hi,

the attached is the patch to add pnp entries to file2alias.c.
i moved the definitions of pnp_device_id and pnp_card_device_id into 
mod_devicetable.h as other devices do.  if you don't like it, i'll try
to revert them and put definitions inside file2alias.c to keep the
changes minimum.

the format of pnp alias is:
	pnp:dXXXYYYY
or
	pnp:cXXXYYYYdXXXYYYY[dXXXYYYY...]
where XXXYYYY is the pnp id with 7 letters (e.g. CTL0031), c shows the
card id, and d means the device id.  multiple device ids will be
listed depending on the driver.

for example,

	alias pnp:dYMH0021* opl3sa2
	alias pnp:cALS0001d@@@0001d@X@0001d@H@0001* snd_als100

Andrey, would it be feasible for hotplug stuff?
