Hmm, I also notices that in ticket 1192, neither the output
of "lspci" nor "lshw" doesn't even output the subsystem ID. The
MODULE_ALIAS() syntax doesn't seem to have a way to specify
subsystem IDs.

I have two Atheros based cards here, one is a D-Link DWL-G650,
one a Proxim 8470-WD. Both have the PCI ID 168C:0013. The
D-Link has the subsystem ID 1186:3a12, the Proxim has 14b7:0a40.

The driver for the Proxim card contains an INF file, which has
this section:

[Vendor]
; DisplayName               Section             DeviceID
; -----------               -------             --------
%LEX.DeviceDesc.CB22ag_G%   = LEX_CB22ag_01,    PCI\VEN_168C&DEV_0013&SUBSYS_0A1014B7
%LEX.DeviceDesc.CB22ag_S%   = LEX_CB22ag_02,    PCI\VEN_168C&DEV_0013&SUBSYS_AA1014B7
%LEX.DeviceDesc.CB22ab_G%   = LEX_CB22ab_01,    PCI\VEN_168C&DEV_0012&SUBSYS_0A001B47
%LEX.DeviceDesc.CB22ab_S%   = LEX_CB22ab_02,    PCI\VEN_168C&DEV_0012&SUBSYS_AA001B47
%LEX.DeviceDesc.CB22ab_A%   = LEX_CB22ab_03,    PCI\VEN_168C&DEV_0012&SUBSYS_1A001B47
%LEX.DeviceDesc.CB22g_G%    = LEX_CB22g_01,     PCI\VEN_168C&DEV_0013&SUBSYS_0A4014B7
%LEX.DeviceDesc.CB22g_S%    = LEX_CB22g_02,     PCI\VEN_168C&DEV_0013&SUBSYS_AA4014B7
%LEX.DeviceDesc.MB22ag%     = LEX_MB22ag_01,    PCI\VEN_168C&DEV_0013&SUBSYS_0A6014B7
%LEX.DeviceDesc.ORiNOCO%    = LEX_ORiNOCO,      PCI\VEN_168C&DEV_0013&SUBSYS_04101467

And, as it turns out, the driver for the Proxim card doesn't
recognize the D-Link card, because it looks not only at the
PCI-ID, but also at the subsystem ID.

It would be interesting to get a list of the subsystem IDs of
misdetected atheros-based WLAN cards.
