The bus design isn't a so big issue, but the problem would be rather the difference of the codec/controller communication. For example, smartlink modem codecs (si3054) and compatibles are already supported in patch_si3054.c. As you can see, the code is really small. AFAIK, the conexant modem codec requires extra communication, a kind of ACK, and thus incompatible with smartlink codecs. Similarly, the intel8x0m driver also doesn't support conexant chips because the conexant codecs need different controls. Ideally, the whole encoding stuff should go to the user-space like slmodemd. I once tried to convince Conexant guys to do that, but they disagreed because of lack of man power. To me, it's hard to imagine because keeping the kernel driver needs more effort...
