It turns out the newer version (in oneiric) of libv4l fixes the
problem.  I installed the libv4l package itself early and it fixed
camorama and cheese, but skype is a 32-bit application so I had to go
through the full distro upgrade to get the relevant package (the
packaging changed between natty and oneiric) installed.  Now this
script

export LD_PRELOAD=/usr/lib32/libv4l/v4l1compat.so
/usr/bin/skype

launches skype with the webcam working right.
