Hi, you should post this on the linux-media mailing list: http://www.linuxtv.org/news.php?entry=2009-01-06.mchehab
I see no recent changes for pwc: http://git.linuxtv.org/v4l-dvb.git?a=history;f=drivers/media/video/pwc;hb=1c1371c2fe53ded8ede3a0404c9415fbf3321328 although I seem to remember a patch posted recently in linux-media for this driver.
