I noticed yesterday that /dev/video0 wasn't being created when I plugged in a webcam. I tried two different webcams to no avail.
With noting to loose, I ran all the RPi updates, including updating the kernel to 3.12.22. All of a sudden my webcams all worked.
Then I noticed that the PiTFT drivers where not being loaded, and that /dev/fb1 was not being created. I then ran through the PiTFT software install which reloaded the kernel drivers again.
After the next reboot, I noticed that /dev/fb1 was back and usable, but /dev/video0 was missing.
To me it seems that loading one of the *.deb files is blocking the creation of /dev/video0 so I can't use both webcam and PiTFT.
Does anyone else have this issue?

You're probably right that one set of modules clobbers the other, but I don't know whether that indicates a fundamental problem or is just a quirk of how things were configured on the build server.
I'll check with the PiTFT team to see if they have more information.

Re: PiTFT drivers blocking /dev/video0
It would be super helpful if you can post the dmesg output from your 'working' setup once the /dev/video0 is created! please post if you can :)
