I use Blag 119k now on my VAIO too but have some little pain with my webcam and cheese. I Install the ricoh driver (Sorry, it's non-free I think) as said in this little howto I wrote on debian French forum (Adapt the files to install to Blag): http://forum.debian-fr.org/viewtopic.php?f=1&t=22944&p=223655&hilit=vaio+ricoh#p223655
When starting cheese I see the webcam light shinning and it stops just before cheese is running. I think it's de cheese bug because it works with all the other webcam application: camorama (Not very interesting), camstream and UCView.
I'm with x86_64 119K.
