This is the memo that I meant - by the way my German appears really,really, really bad - the German version appears to be copied from the USA version. Of course this is just one of
many memos between the participants. I note that the memos that you put
forward, however, seem to show that the "Jewish problem" was being
handled in ways other than gas chambers - ie deportation or sterilization
( both rather extreme injustices but not deadly - a little reading
shows that Hitler, Himmler,etc... could be quite squimish about 
killing people (ie the wiki article "Night and Fog" sugggests as much).
There has been attempts to question this memo's provenace, however, this
memo is just one of several that follow the same theme - "leave the Jewish problem alone, at
least till the war is over". If there was any gassing - or any murder of 
Jews - it was being done behind Hitler's back ( and  the backs of any
loyal/ambitious Hitlerites ), a not very plausible scenario, but the one 
the memos would force on believers. 

The memo I meant was:

"Mr Reich Minister Lammers informed me that the Führer had repeatedly
declared to him that he wants to hear that the Solution of the Jewish
Problem has been postponed until after the war is over. That being so,
the current discussions are of purely theoretical value, in Mr Reich
Minister Lammers' opinion. He will moreover take pains to ensure that,
whatever else happens, no fundamental decisions are taken without his
knowledge in consequence of a surprise briefing by any third party."
July 1942

Unless some scholar can find a memo dated after this that reverses the 
policy - and I believe all the memos and actions taken by various people 
(ie Himmler,Luther, Morgan, etc ) instead tend to confirm the policy - 
it appears that finding a memo with a Hitler ( ie official ) connection
to the Holocaust is just a dream. ( Irving's $1,000 - or whatever amount - seems safe) I hope this memo can make it into the article - ( he may have been a nasty guy but honestly he was 
probably just a bureaucrat, that seems to be the treatment he 
received after the war by people on the scene). 
Browsing/reading the German language wikipedia - I am not really a good
German reader but correct me if you are - version of this article it
appears they also avoid the relevant memo, but of course they have the
fear of prosecution over their heads. In America our reluctance, at least, isn't legal. 
Finding the Luther memo, it appears this memo is of an even later date. 
It is even more revealing as to what the policy toward Jews was during the war.
All Jews were to be expelled from Europe after the war was over - so it 
appears Hitler was not talking gas chambers,etc quite late in the war. 
Memos of this sort seem to crowd all the Holocaust gassing,etc into a
very small time frame - an impossibly small time frame, probably why the 
memos are ignored by all right thinking people.  

PS I just found out that the Luther memo has a long history. It has been ignored 
since at least the 1970s. I thought this was a relatively recent discovery
by scholars etc - it appears to just be an old unanswerable embarrasment 
to the Holocaust story. Thanks for pushing me to search harder. One of the troubles
with trying to hide or falsify history appears to be that it takes very little work
by very unknowledgeable people ( ie me )  to discover the truth. I found most of the
information that seems more plausible than the "official" story by just hitting ENTER
on more than the the first page of search engine results.
