[Bug 379780] Re: CD-ROM polling on some Optiarc drives causes high CPU usage

Martin Pitt in comment #72 linked to the commit with instructions on how
to fix this issue. Polling is not disabled by default because it stops
media detection and does not cause issues for most people. Please follow
his instructions to disable polling using udev.

Note that udev has replaced hal in this regard in Lucid. The fdi file
that hal-disable-polling will have no effect. Thus, the udev rule Martin
pointed out must be used.
