Would your hardware also not support sse? In any case I don't think anyone is planning on completely abandoning non-sse x86, but personally I think it's reasonable to remove stuff like the fistp assembly conversion in favor of things producing faster code on more modern cpus, leaving just generic c code for those oldtimers (obviously, you could argue those old cpus need such optimizations the most, but really, I don't know how many people need a uptodate mesa on a cpu not newer than Pentium II or Athlon (non-XP)). Well maybe not actively remove such optimizations but if they get in the way. That's just my opinion though.
