The more I think about this, the less I like the idea.  I really don't 
like the idea of having revision numbers which no longer increase with 
commit date (i.e. having revisions 1-250,000 correspond to the existing 
src tree, 250,000-300,000 being the imported doc tree, and then the 
combined repo being 300,001 onwards).

I think it is much nicer to have two separate repositories, in which 
revision 1 corresponds to the start of each tree.  I don't see any real 
advantage in combining them now, to be honest.

Combining doc and www more closely, however, I do see the benefit of.  
However, currently we don't (and have no need to) branch the www tree with 
each release.  If we combine them, we would be - even though we probably 
don't wish to.

It may actually be easier, as all the infrastructure from the src repo can 
possibly be reused easily.  Combining them may be harder as more work 
would presumably need to be done on sorting out ACLs for src and doc 
committers, etc?

An argument could be made that by keeping them separate then it reduces 
the overhead for people wishing to contribute.  People wanting to commit a 
kernel patch need a copy of the website on their disk just as much as 
people wanting to edit the website need the kernel source.  Having them 
separate allows these two distinct groups to not need to check out reams 
of data they don't actually need.

Absolutely, I think the conversion to SVN is a certainty, for this and a 
lot of other reasons.
