But now camorama has gained support for autodetecting problems with
MMAP support.

At least for Asus T101HA, camorama is now working with atomisp.

I addressed those issues. The implementation is not 100%, but it is good
enough for camorama to start working.

I didn't touch it. So, camorama should be called the first time with:

	camorama -d /dev/video2

in order for it to work. As camorama memorizes the last used camera,
it will pick /dev/video2 if called later without any parameters.
