That's because you're running a very recent intel driver and server
(enough to get DRI for multiple servers) but an already old kernel.

I just tested on my i945 laptop running intel 2.9.0, xserver 1.6.4 and
kernel 2.6.32-rc*. KMS obviously works fine (I always use it since
2.6.31-rc) and DRI seems to work well with multiple Xserver. So I am
just closing this bug. Feel free to reopen if you can reproduce this
problem with at least 2.6.31 and KMS working (KMS not working is another
problem).
