Is sse3 required for ATI CAL support?

It would appear that sse3 is used according to a post here near the bottom.  Quoting from the post: "Program received signal SIGILL, Illegal instruction.  For every sample program...  and similarly now for CAL (which actually sort-of worked with an older driver under it). I assume this is because it is hitting an SSE3 instruction?"

The poster was trying to get an AGP version of the 4650 to work on an older cpu.  Exactly like what I was thinking about at one time.  He did not get an answer as to whether the library was avilable w/o the sse3

Raistmer:
Currently SSE3 support considered as required for ATI AP based on OpenCL.
BUT SSE3 not required for CAL itself. Moreover, there is Brook+-based hybrid ATI/CPU app that supports SSE-only CPUs. One can download it from beta forum on this site.
