x264 [info]: using cpu capabilities: none!

Is this the expected behavior? My yasm version is much newer than others
I've read to cause troubles in cpu detections. I've tried to force
capabilities with --asm, but I did not find numbers for MMX and SSE.

I'm running ubuntu 10.10 Maverick. Some details below.
