Comment 220 for bug 395932

Thank you for this patch but with my i855GM the messages :
"(==) intel(0): Intel XvMC decoder disabled
(WW) intel(0): Disabling Xv because no adaptors could be initialized."
are alway present.
for replace the driver of lucid, I open synaptic and i force the version
with the version of the ppa and I log out the session.
I do this with a live cd of lucid (daily of 26 march).
is what I have done well?
sorry for my english
