I use gcc 3.3.3 at the moment, and I think 3.3.5 is the version that
comes with the SuSE version that my collegues in Austin tends to use
(9.x I think), so I would say that's fine - unless of course that
particular version of debian build is broken... 

Can you do objdump -d on your xen-syms (in ...<xen-source>/xen) - just
the first 15-20 lines should be enough to see that it's looking about
right - just mail it to me, not the list, as I don't think most of the
list will appreciate assmebly dumps ;-)
