Ok, then we'll need to look into things that are not added at all.

The following might be the one you're missing:
CONFIG_XEN_KEYBOARD=y

It is in my config, but not in yours.

Could have a few reasons:
- I have the "compatibility" for xen reduced to 3.4 or higher. Not sure
which xen-version is included in yours.
- I do not have support for an initramfs or similar in there
- I specified the CPU-type in the kernel (It's not a generic one)

Did you check the logs for xend, system (messages) and others?

Looking forward to the result.
