I don't actually have such a "full" history. It would be wonderful if 
somebody took the time to try to piece such a thing together (and git 
actually makes that a _lot_ easier than some other SCM's, because you can 
just import random versions in any order, and then re-stich just the 
commit history when you add a new thing in the middle, without generating 
any new trees or deltas or anything strange at all).

But it's a lot of work. I tried to do a "Linux-Historic" archive about a 
year ago (and imported some of the old kernels I had), but I gave up, just 
because it was such a pain to try to do a good job and try to find old 
release notes etc to import into the changelogs etc. 

Oh, well.

So the only "old" history I have is indeed that BK conversion by Thomas 
Gleixner. Any pre-BK stuff only exists as patches and tar-balls on various 
ftp sites (and I don't have any magic repository of my own, so everybody 
else can do exactly as well as I could, with possibly the exception that I 
might remember some random details about some old release history - but 
considering my memory, that's pretty unlikely too. Google is your friend)
