The lack of support for modern features -- Line State Monitoring, Feature Key Synchronization, Shared Lines / Shared Call Appearance, N-Way conferencing -- have convinced me that the best thing to do with a Cisco 79x0 phone is to Ebay them to someone using Call Manager. Then buy a modern SIP phone.

The 7940 and 7960 are the exact same thing except for the line key count. They both are fairly reliable with "Non-CM" SIP in 8.X and on as long as you stay away from any remotely fancy features like shared lines (SUBSCRIBE) or such.
The 7941 and 61 however I've never seen the non-CM SIP FW for. If it is a CM-SIP FW, you may want to check this 7970 reference and some of the related articles for XML config help:

So...if you value your time and sanity... don't support sip with cisco 79xx series.
If you wish to do this purely for Fun.... Good luck, hopefully you have a lot of time on your hands and a great amount of patience.
Eh, it's not so bad with the 7960s. A bit of a pain, but the high-quality hardware makes it worth it.
The 7940s? Yeah, I wouldn't touch that.
