Well *sure* we tested it, but that was on IOS version 12.3.(TPS)/J-woowhoo Enterprise, you're running 12.3.(TPS)/J-woowhoo Enterprise *Plus* you silly goose.
The article says that there's more than 15,000 supported builds out there... Damn, I knew that there were an ungodly number, but I had no idea it was that extreme!
(somewhat) Funny war story to cheer up the router gods out there: I was working at a small ISP back in the late 90's (the kind of ISP that bought used 2500s and 3640s but no support contracts, so you fret over a collection of IOS .bin files). We turned up a bonded pair of T1s from a tier 1 ISP who will remain nameless, and had some speed issues.
To test the line speeds, their tech support guys directed us to a private FTP server. The server had a fat pipe to their backbone, and was dedicated to customers like us. SOP was to upload and download a fairly good size (say several MB) file directly from your router and see what transfer rates you got (directly from the router so that they weren't stuck debugging your internal network issues).
Hmmm, now what files would one have handy on the router that fit the size requirements? Bingo! IOS images. Since the site was semi private, they had a nice big shared directory with o+rw, which happened to have some images with more bells and whistles than my stock ones.
