Hi Brice,
thanks for your answer and sorry for the late reply, i was away.

well, not compiz but opengl which uses dri. Actually the screensaver is an
opengl one, but the hangs happens also if i switch vt's immediately after
login. I don't think i have other special effects but i will try starting
X and then glxgears.
BTW, for me it happens with a _wired_ connection, although the ipw2200 (+
vanilla kernel 2.6.21.* right now) are loaded.
I will also try unloading them. But as said previously, it works like a
charm with the older i810 package...

what to do there, wait for an update or try to compensate in xorg.conf?

fine for the first 3, the clone options where needed (ok, with i810, right)
to get the dualhead (lcd + external beamer) to work.
