Good news and bad news.
I've managed to get my quickcam messenger (0x08f6) working, but with the qc-usb-messenger-1.8 driver (qcmessenger.ko), not the 0.6.6 one on which Ubuntu's quickcam.ko is based.
I've spent an hour or so comparing the sources to see if I can fix the 0.6.6
driver, but it ain't as simple as applying the same fixes or some simple
fixes to qc_stv_set() or somesuch.
See above (https://bugs.launchpad.net/ubuntu/+source/linux-source-2.6.15/+bug/22070/comments/21) for more details
I haven't got the hardware specs, which leaves me out of my depth to see the relevant differences
between both drivers.

 Ubuntu (based on qc-usb-0.6.6, sensors: hdcs1000, hdcs1020, pb0100, vv6410):
0x046D:0x0840           QuickCam Express
0x046D:0x0850           LEGO cam / QuickCam Web
0x046D:0x0870           Dexxa WebCam USB
0x046D:0x08F6           Logitech QuickCam Messenger
 but in fact, the Messenger won't work with this driver.
 qc-usb-messenger-1.8 (vv6450 sensor) :
0x046D:0x08F0           QuickCam Messenger   
0x046D:0x08F5           QuickCam Communicate   
0x046D:0x08F6           QuickCam Messenger (new)
0x046D:0x08DA           QuickCam Messenger (new)
Will work, get the sources here: http://home.mag.cx/messenger/
Then apply the patch i've attached here:

patch -p1 < qc-usb-messenger-1.8_2.6.27-v4l.patch
make all
insmod ./qcmessenger.ko

You will get a V4L device (not a V4L2) and it works in xawtv and Ekiga.

The other bad news is that the current Skype version ( will crash when you will try to use the webcam.
Other people experienced the same, looks like there's no fix for that (yet).
