It's not in 3.9.17, not even in the XFree CVS yet,
unfortunately. But yes, that seems to be the problem.

There seem to be some SIGIO-related problems between silken
mouse and DRI in 3.9.17. I sent the details to XFree devel
mailing list, but here it is in short.

- DRI adds a SIGIO-handler with fd X (/dev/dri/card0)
- Event system adds a SIGIO-handler with fd Y (/dev/psaux)
- first SIGIO arrives, from mouse
- SIGIO handler calls select with fdset containing both fd's X
  and Y
- select returns with value 2 and both fd's set
- SIGIO-handler calls the DRI SIGIO-handler, which tries to read 
  from fd X
- the read _BLOCKS_ and server freezes
- the server is not dead as I can pass SIGINT to it and it dies
  gracefully
