I didn't read xen-users list for some time, so I missed some things.

But, indeed, it shows something after appending console=hvc, but still, 
it doesn't start - does it sound familiar (below)?
I tried to search the list, but wasn't very successful in finding an 
answer (other than it must be a problem on UP kernels).
