Yup.

{0}:/usr/src/kernel/qc-usb-0.6.0>lsmod
Module                  Size  Used by
quickcam               65180  0 
8250                   21216  0 
serial_core            23488  1 8250
snd_emu10k1            95620  1 


I also tried with the pwc module.  No go.

This struck me as odd though.

drivers/usb/core/usb.c: registered new driver quickcam
request_module: failed /sbin/modprobe -- char-major-81-0. error = 256

I did a "rm -f /dev/video /dev/video0 /dev/video1" and re-installed the
module and found this in dmesg:

drivers/usb/core/usb.c: deregistering driver quickcam
drivers/usb/core/usb.c: registered new driver quickcam
