If you're using the old kernel you can continue to use the old initrd.
There's one possible change though: You might need to add "pci=nomsi"
to kernel parameter.

Should be. I forgot what the command is (is it make tools?) try
looking at README (if available) or makefile.
Anyway, even if it builds and install a new kernel, you can simply
choose not to use the new (2.6.18) kernel and use your old suse kernel
instead.

In general, yes, the hypervisor and kernel is connected. However newer
xen kernel has a compatibility option, by default selected to 3.0.2.
This means that as long as your hypervisor and userland has the same
version, and it's >= 3.0.2, it should work (minus some
version-specific feature)
I've been using Redhat's kernel-xen (built against Redhat's Xen
3.1.2+) with Xen 3.3 and 3.4, and it works great.
