Philips webcam PVC740K not working on latest kernel

[Jaap A. Haitsma]

My Philips webcam PVC740lk, which works beautifully under RH9.0, does 
not work with the latest kernel: 2.4.22-1.2087.nptl. GnomeMeeting says 
that the pwc driver does not support YUV420P

I did some further tests. I downloaded (from kernel.org) and compiled 
2.4.20 and 2.4.22 kernel myself. The camera works when I run 2.4.20, but
I get the same problem under my 2.4.22 as in the 2.4.22-1.2087 provided 
by fedora.

Jaap.

P.S. Arjan I cc'd you, because I saw on the web that there already have 
been some issues with the philips webcams in 2.4.22 and you've been 
handling these
