Definitely sounds like Xenolinux and Xen are out of sync. XL is
probably sending the wrong control-interface version number to Xen. 
Are you sure you are building both, that XL is taking teh correct
hypervisor-ifs header files; and that you are booting the two most
recent built images?

Okay, I've checked in a fix for this to 1.2 and to unstable.
The syntax 'ARCH=xeno make xxxx' will work again now.
You should find that 'ARCH=xeno make mrproper oldconfig dep bzImage'
does the right thing...
