 No, certainly not "after the deed" (it was too late last night, I guess).
 I will dig further to find where this originates - I guess we somewhere
 deliver values differently to userland with 64bit kernels and userland
 calculates the addresses based on that.
 
 Slightly tricky to find if you can't invoke ktrace (because the invoking
 shell already dies). More kernel debugging needed...
