I've just tested Debian version 2.6.32-5-686 (which I think corresponds
roughly with 2.6.32.41, at least according to changelog.Debian.gz).
Unfortunately the corruption on the external display is still present
under the same conditions (no corruption when nothing changes on either
display; large corruptions on motion).  Is that a recent enough kernel
for the test to be interesting, or should I be building my own using
higher patches (i.e. is there relevant stuff between .41 and .45 that I
should be looking at?  A quick grep for "i915" didn't suggest so, but I
could be wrong.)

Thanks,

Christophe
