Which IOS release supports MFR on a Cisco 2621?

I can't track down which IOS release (if any) supports MFR on a Cisco

2621 (note: not XM). The Cisco docs claim that it's supported as of 12.2(8)T, but when I installed 12.2(15)T16 on a 262x, the MFR commands (specifically "show frame-relay multilink") didn't show up. Ditto for 12.3(15a). This was using the IP feature set in both cases.

The 12.3 doc below does say that MFR is supported on 2600 routers (see section 10.3)...:

....but I can't find any 12.3 release that supports them.

Also, how would I figure this out? The Cisco Feature Navigator didn't help, because MFR itself isn't listed as a feature that can be searched (MFR Variable Bandwidth, MFR over L2TPv3/AToM, and MFR Stateful Switchover, yes; just plain old MFR, no).
