I wasn't able to rule out PAT from the suse bugreports POV, as we have PAT 
enabled both for 32bit and 64bit x86.

If Ubuntu has it disabled also for 64bit x86 (where do these guys have 
.config files to check?), I think we can definitely rule out PAT, as there 
has been at least one report from Ubuntu user on this very issue.
