Comment 2 for bug 509219

If someone has this hardware and wants to test I applied patch 35743 from bugzilla.kernel.org and added pm_qos_requirement to bttv driver (Lucid kernel). What it does is effectively that c1e is disabled for the time of capturing. The 35743 patch might be useful for some other drivers that require low latency like wireless drivers that use pm_qos and c1e breaks them.
