Video4Linux installation

I 'm running Angstrom distribution (console only) on BeagleBoard-xM. Image was build on Narcissus, with Bootloader Files (x-load/u-boot/scripts) added. I want to connect a USB webcam (Logitech Pro 9000). Problem is that device isn't recognised by the kernel (/dev/video0 not listed). I have some questions: 1. Is Video4Linux the driver I 'm looking for? 2. Should I had include a toolchain on Narcissus, in order to build Video4Linux, before installing it? (any installation guide would really be appreciated). 3. Is there any way instead, to rebuild Angstrom image including the appropriate drivers? Any help, would be really appreciated.
