There are two drivers for those cameras:

Mhz 386 don't work with it.
-the 2.x driver at alpha.dyndns.com/ov511. This is the only one who
works with
the late models who used this chip (and the ones who are still useful).
Probelm is that the author has not updated its site in two years and
that it no longer compiles with present day kernel. I fixed it for
2.6.16 kernels and sent the patches to the author but got no answer.
And kernel 2.6.24 (I think) broke it again (or more exactly made it
no longer compile).
Question if I fix it again what are the chances it ends in Fedora? How
are orphaned drivers handled in the kernel? Someone, who doesn't seem
to be the original author, has been ensuring the 1.x continues compiling
in 2.6.27 despite the changes in interface.

Hi JF,
Most webcam based driver development now a days happens within / on top of the
gspcav2 framework, which has been merged into the 2.6.27 kernel. gspcav2
already supports ov519 based cams, adding support to the existing driver for
ov518 based cams should be easy, as those are mostly the same. The big
difference is that ov518 based cams use a slightly non standard form of JPEG
compression one of the first things that need doing is adding support for this
compression to libv4l.
Would you be interested in working on this? Here are some references explaining
how to get the latest gspca driver, and about the why, how and what of libv4l
