Short answer:
linux-image-2.6.32-5-xen-amd64_2.6.32-48squeeze4~ijc0_amd64.deb
solves my problem (bonding packet loss).
Tests:
- 2 nodes with base install of squeeze
- apt-get install xen-linux-system ifenslave-2.6
- each node has one single head and one dual head NIC:

- the dual head NICs are configured as bond1 pointopoint:

Test1:
node xen01 runs linux-image-2.6.32-5-xen-amd64_2.6.32-45_amd64
node xen02 runs linux-image-2.6.32-5-xen-amd64_2.6.32-48squeeze3_amd64

Test2:

Test3:

node xen02 runs linux-image-2.6.32-5-xen-

Test4:
both nodes run linux-image-2.6.32-5-xen-

Obviously these tests say nothing about the other reported problems.
