I switched to Breezy recently and ov511 support is *STILL* broken, for a camera
that works flawlessly on any other distro I've used.

Here's the dmesg from a startup with the camera (A Creative "Webcam Go", model
PD0040) connected:

[4294722.255000] drivers/usb/media/ov511.c: USB OV518 video device found
[4294722.257000] drivers/usb/media/ov511.c: Device revision 9
[4294722.269000] drivers/usb/media/ov511.c: Compression required with
OV518...enabling
[4294723.617000] drivers/usb/media/ov511.c: Sensor is an OV6630AE
[4294723.821000] drivers/usb/media/ov511.c: Device at usb-0000:00:1d.0-1
registered to minor 0
[4294723.821000] usbcore: registered new driver ov511
[4294723.821000] drivers/usb/media/ov511.c: v1.64 for Linux 2.5 : ov511 USB
Camera Driver

All looks good. Note the line "Compression required with OV518...enabling" -
this is exactly what should happen.

Now, in a terminal, I type:

 $ cat /dev/video0

...and receive the following error, same as on Hoary:

 cat: /dev/video0: Function not implemented

If I check dmesg immediately after running `cat`, the following line has been added:

[4311806.230000] drivers/usb/media/ov511.c: No decompressor available

So despite what the initial dmesg output says, the module is getting confused
somehow. The ov518_decomp module, which is present in the ov511-source package,
should handle decompression of the jpeg stream. I can't verify that it works
though since make-kpkg does not seem to work properly on Breezy either (gah!).

I also found a forum post in which a user has the same problem, and solves it by
installing the 2.2x series module:
http://www.linuxquestions.org/questions/history/334689 .

Hope this helps - this bug has been stale for months, and I miss my webcam.
