Well my system is an ML115 but probably otherwise identical. I haven't
disabled any large send options at all anywhere to get my

Maybe you need to install 'xenstore-utils'?
# dpkg -S xenstore-ls
xenstore-utils: /usr/bin/xenstore-ls
xen-utils-3.1-1: /usr/lib/xen-3.1-1/bin/xenstore-ls
xen-utils-unstable: /usr/lib/xen-unstable/bin/xenstore-ls

I'm using Xen 3.2.something from etch-backports. My kernel is
2.6.18-xen-amd64 which I assume is built from the same source as yours.

That is only udp large send offload. The one you want to notice is 'tcp
segmentation offload', which is 'on' on my system.
