Actually, Cisco supports TKIP as well. Cisco originally came out with their own version when they needed to get a 
Fluhrer-Mantin-Shamir countermeasure into customers' hands quickly, before the standards body was ready. That is the 
Cisco algorithm we now call "CKIP." But, Cisco also supports the standard version of TKIP, and recommends it, because 
it is stronger and it is interoperable. Thus, I believe your concerns about non-compatibility are now obsolete. 

I found this documented at:
http://www.cisco.com/en/US/products/hw/wireless/ps4570/products_configuration_guide_chapter09186a0080184aca.html
Table 1 of this link shows when CKIP, TKIP, and WPA were released:
http://www.cisco.com/en/US/products/hw/wireless/ps4555/prod_release_note09186a00801d7255.html#84464

There is probably a more concise link somewhere (I'm not in the wirless networking group), but I think those covers it.

Thanks,
