If you're getting serial output from Xen, then the parameters on
the Xen command line must be OK. You should get console ouput
from xenolinux with console=xencons0

As I recall, these are in 2.6, but not 2.4 (unless you have a
redhat megapatch kernel).

libc decides at runtime which of the many thread local storage
schemes to use based on a wide range of inputs: kernel version,
syscall existence, cpu feature set, ldlibary cache, phase of the
moon, price of eggs, etc.

I expect it's using the one that involves the 'modify_ldt'
syscall, but might be using fs/gs in some new and exciting way
that we've yet to encounter on our systems...
