For reference, Mandriva solves sound-after-suspend with some shell
scripts that remove and reload some sound modules, as well as possibly
restarting some programs using the sound device. This has worked
reliably for me on a T20 with 2006. The scripts they use are GPL and
available here:

(See "sound" in "suspend.d").

All video, or just DVDs? I noticed and documented that "DMA" doesn't
seem to come back after a suspend on the ThinkPad T20, which is the
cause of DVDs not playing well after suspend/resume.

(The DMA details are buried somewhere else on the ThinkWiki website.

Thanks for the thorough testing and report!
