On an 877 and an 871 with 12.4(15)T1 and SDM 2.4.1, IPS version 5 signatures are not showing in the 'Configure-->IPS' screen. Anyone else experiencing this behavior?
See attached doc.

Router memory and resource constraints prevent a router from loading all Cisco IOS IPS signatures. Thus, it is recommended that you load only a selected set of signatures that are defined by the categories. Because the categories are applied in a "top-down" order, you should first retire all signatures, followed by "unretiring" specific categories. Retiring signatures enables the router to load information for all signatures, but the router will not build the parallel scanning data structure.
Retired signatures are not scanned by Cisco IOS IPS, so they will not fire alarms. If a signature is irrelevant to your network or if you want to save router memory, you should retire signatures, as appropriate

I have exactly the same problem, but I was unable to find a solution yet. My router is 1811 and has 384 MB RAM, so I think that memory is no issue. Any help?

I think it's a bug in 12.4(15)T1
