Great news Tristan!  We do not have ia64 systems available for testing but we are very interested in how your ACM port is going.

Thanks. Please submit the patch for creating the dump in the ACM (if you have one) as well.

I tried the tools/security patch on my laptop and it works fine on my x86 Xen.

Please make sure the 'alignment-hole' in the policy reference is filled deterministically (e.g., with \'0'). The same source policy should always yield the same binary policy.
