With 2.6.27 this stills an issue. Upgraded from 8.04 to 8.10.a5 and then
all auto-updates as they came.

$ uname -a
Linux NolarBook 2.6.27-3-generic #1 SMP Wed Sep 10 16:02:00 UTC 2008 i686 
GNU/Linux

$ dmesg | grep uvcvideo
[   13.500023] uvcvideo: Found UVC 1.00 device Laptop Integrated Webcam 
(05a9:2640)
[   13.509776] uvcvideo: Failed to query (135) UVC control 1 (unit 0) : -32

[   13.509914] uvcvideo: Failed to initialize the device (-5).
[   13.510200] usbcore: registered new interface driver uvcvideo


After that, webcam still doesn't work (regardless of what the last line says).

Doing "rmmod uvcvideo && modprobe uvcvideo" solves the problem. And it
says:

[ 6717.305615] usbcore: deregistering interface driver uvcvideo
[ 6719.813625] uvcvideo: Found UVC 1.00 device Laptop Integrated Webcam

(exp. 26).
[ 6720.885163] usbcore: registered new interface driver uvcvideo

After that it works. Probablhy the initial suggestion about
blacklisted+/etc/modules will work. I'll check later.
