No, CONFIG_IA32_SUPPORT does not work.  There is at least one ia32
register that needs virtualization and all of the ia32 state
save/restore
is either missing or has never been tested.  It's possible that
it could be made to work, but I don't think anyone is working
on it (or planning to work on it).

The boot output from Xen is going to a different place, depending
on what you specified for the console.  Specifying console=vga
for domain0 may show you the Linux output, but may cause problems
for Xen (I think it works on Intel boxes but hasn't been tested
on HP boxes).

All of the console stuff will change shortly due to upstream changes
from Xen/x86.  More on that shortly.
