You have built the Intel driver in the kernel correct? It is telling you
you didn't build KMS support in your kernel and showing you what needs
to be set in your kernel.

This will probably correct your problem #3, by the way.

The new link is /etc/timezone, not /etc/localtime. I would think if you
renamed it that problem will go away?

Try building KMS support (and the Intel driver if you haven't) in the
kernel and report back.
