[c-nsp] 2610 + NM-16ESW -- What IOS supports this card?

[Eric Cables]

I have an old 2610 router that I am attempting to use an NM-16ESW card in,
but despite my efforts I cannot find an IOS image that supports this card.
Cisco's documentation (
http://www.cisco.com/en/US/prod/collateral/routers/ps259/product_data_sheet09186a00801aca3e.html)
indicates that 12.2(8)T and above should support the module in a 2600 series
router, but there are no downloadable 12.2T images on Cisco.com, and though
I have tried multiple 12.3 images, none have worked.

Here are a couple of versions that I've tried without success:
c2600-ik9o3s3-mz.123-26.bin
c2600-ik9o3s3-mz.123-18a.bin

Here is what I see after inserting the module and booting up (relevant
messages):
smart init is sizing iomem
  ID            MEMORY_REQ                 TYPE
000091          0X0008B800 C2600 single Ethernet

If any of the above Memory Requirements are
"UNKNOWN", you may be using an unsupported
configuration or there is a software problem and
system operation may be compromised.

%PA-3-NOTSUPPORTED: PA in slot1 (Unknown (type 681)) is not supported on
this image.
           Please issue "show diag" in fully loaded IOS image
           to get the PA's information and verify if it is supported
           by this image, a newer version may be needed.

<-- snip --

I've opened a ticket with TAC, to try and get an IOS recommendation, but I
was told that the 2610 has reached the "end of support" cycle, meaning I'm
SOL.  Additionally, the Software Adviser does not return any available
images for the platform & hardware combination.

If anyone has a 2600 series router (non-XM) that has a working NM-16ESW
module, can you please provide the IOS version (if available to download on
Cisco.com), or send me the image itself?  The 2610's memory is maxed out
(64MB) with 16MB of flash.

Thanks,
