Webcam Problem

["Stephen P. Molnar" <s.molnar@sbcglobal.net>]

Debian 64 bit Wheezy/sid in a VM on my Dell Laptop. I know that he
webcam works in Linux. 

When I attempt to apply Camera default settings in Kamerka I get the
message 'Could not connect to V4L device!' 

I have found
http://wiki.debian.org/AtiHowTo#Installing_proprietary_firmware but am
not sure about implementing the instructions.

I have found lspci -v | grep VGA
00:02.0 VGA compatible controller: InnoTek Systemberatung GmbH
VirtualBox Graphics Adapter (prog-if 00 [VGA controller])

Also,

comp@debian:~$ grep DRM_RADEON /boot/config-3.2.0-4-amd64
CONFIG_DRM_RADEON=m
CONFIG_DRM_RADEON_KMS=y
comp@debian:~$ grep AGP /boot/config-3.2.0-4-amd64
CONFIG_AGP=y
CONFIG_AGP_AMD64=y
CONFIG_AGP_INTEL=y
CONFIG_AGP_SIS=y
CONFIG_AGP_VIA=y

However, according to the HowTo

CONFIG_AGP=y
CONFIG_AGP_AMD64=y
CONFIG_AGP_INTEL=m
CONFIG_AGP_SIS=m
CONFIG_AGP_VIA=m

Question #1:  Am I on the right track?

Question #2:  Is it safe to change settings from 'y' to 'm' in the
config file?

I'll be the first to admit that I don't have the faintest idea as to
what I'm doing when it comes to hardware.

Any assistance will be much appreciated.

Thanks in advance.
