This all depends on what Xorg server version and intel driver version is
available there. I can tell you that i855 does support DRI. The stability
depends on an amount of factors like xserver, parameters, system you run it
on, etc...

I think you are talking about Linux kernel drivers, those are important but
it's not the only piece of SW you will need. I think i830 is deprecated in
favour of i915.

You are coming to upstream, so possible little people here will know about
your exact distro problems.

I think it's possible using driconf.

What hardware?

For such a generic question a lot of info should be provided. I suggest
asking first on #yourdistro or a mailing list related to it and then come
here with specific xorg problems.
