Malfoy Sr's Intent with TMR's Diary (CoS)

To go with three suggestions by Hannah (see message 113015  Re: What 
were the Malfoys DOING there?), I've just posted a 4th possible 
motivation behind Lucius Malfoy putting Riddle's diary into 
circulation at the start of CoS, namely as a means to attack Harry.

Hannah's suggestions were:

<snip>
Hannah now: The real question here is what Lucius Malfoy was hoping
to achieve with the diary. I can think of three possibilities:
1. Restore LV to power through diary Tom
2. Kill off as many mudbloods as possible, and get the school shut
down.
3. Discredit Arthur Weasley, hopefully killing some mudbloods along
the way.

Killing Harry may have arisen by success in option 1 and perhaps 
this WAS LM's thinking. It all begs the question of what LM 
knows/knew about how the diary works and what it could do. 

Thinking about this leads me (brainstorming here) to a range of 
thoughts (probably not all original)

LM may simply have known that the diary could be a means to open the 
chamber, but if so how was that a *direct* threat to Harry and why 
should Dobby choose Harry to warn rather than all Hogwart's 
students? 

Does LM really want Voldemort back? (not my original idea I freely 
acknowledge). But if not, what is his own agenda for wanting to kill 
harry and/or open the chamber and/or reincarnating Tom Riddle?

WOULD *the* Voldemort, as opposed to *a* Voldemort, have come back 
had Harry not gone to the rescue and TMR managed to regain a 
physical body? 

Clearly Diary!Tom knows what his future self, as LV, had achieved to 
that point and what went on with Harry at GH, although maybe (as 
others have pointed out) only Ginny's knowledge in these respects. 
Would a reincarnated Tom know all the magic etc that Vapor!Mort knew 
or would he have to go through it all again - with LM as mentor - 
now there's an interesting reversal. I don't think this is clear 
because of Diary!Tom stating that Voldemort is 'my past, present and 
future'. 

In GoF LV, when he *does* finally return to physicality, makes a 
comment along the lines of how come you never looked for me Lucius? 
Does *that* LV not know what LM did (or tried to do) in CoS? Why 
does he single out Avery for punishment, not Lucius? LV goes on to 
mention his thwarting as Quirrel!Mort by Harry, but skips then to 
Pettigrew's return and does not mention CoS or Diary!Tom. So, is he 
aware of what went on in CoS? Seemingly not, at least in the 
graveyard scene.   

Did LV leave bits of his persona in other objects (possibly what JKR 
means by what he did to make himself immortal - assuming he is, 
which isn't clear) or in other ways. 

Some of his power certainly seems to have been ceded to Harry at GH, 
so has this been lost or was it gained back at his rebirthing etc 
etc? 

Was it necessary to have the chamber and its magic (secret*s*)
involved in order for the diary to regenerate Tom? If not, then why 
hadn't LM simply used the diary earlier to bring back his 'master'?
