I've downloaded the Fedora 18 .iso file, unfortunately the USB stick
created is not able to boot. According to wikipedia the kernel used in
Fedora 18 is 3.6.10. I've downloaded the source an scanned it for
"atomisp" and "ov2680" - but did not find anything. After some more
research I've found a forum post about a patched kernel from timesys:

  "... I have got a copy of atomisp driver from Timesys, which named
  kernel-3.8.0-1.src.rpm. The driver be written by intel. But the
  driver can not be correctly work on my platfrom(E3827). So i come to
  be suspicious of the compatibility. And i want to know whether the
  driver can be suitable for my platfrom?

  Drivers infomation as blow:
  - The version of atomisp driver: BYT_LSP_3.8_ISP_2013-12-06.patch
  - The version of atomisp firmware: iaisp_2400_css.bin ..."

It looks as if this src.rpm is available here:
http://repository.timesys.com/buildsources/fedora/18/x86_64/source/ 

I'll now figure out how to open the .rpm package to have a look if
there is something about atomisp.
