I have tested the latest upstream kernel. The problem still persists in
most applications (cheese, vlc, qv4l2, skype), but is fixed in xawtv.
Cheese outputs the following new warnings in the terminal:
nvfx_screen_get_param:95 - Warning: unknown PIPE_CAP 30
nvfx_screen_get_param:95 - Warning: unknown PIPE_CAP 30
nvfx_screen_get_param:95 - Warning: unknown PIPE_CAP 55

xawtv, while capturing the video correctly(!), also outputs such warnings:
This is xawtv-3.102, running on Linux/i686 (3.9.0-030900rc8-generic)

VLC's errors change as well:

[0xb5207818] v4l2 access error: device does not support mmap I/O
