This is the error I get with the OpenCV SVN as of today (Aug 3, 2009):
libv4l2: error dequeuing buf: Resource temporarily unavailable

This pointed me here: https://bugs.launchpad.net/ubuntu/+source/libv4l/+bug/303174
and then here: https://bugs.launchpad.net/ubuntu/+source/libv4l/+bug/260918

Using their "workaround" (LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so), I've been getting this output:

libv4l2: error dequeuing buf: Input/output error
VIDIOC_DQBUF: Input/output error
