> Is there a way to use SSE when available and x86 when it's not.

Probably, but I don't think there is any point doing so. The main
benefit of SSE2 is to get higher performance on floating point intensive
code, which no pure Python code could be regarded as (the CPU cycles
elapsed between two FP instructions would dwarf the cost of executing
the FP instructions themselves).

The situation is different for specialized packages like numpy, but
their decisions need not be the same as ours AFAIK.
