It is quite natural to think this might be a problem, but in fact it is not:

(a) The very reason the OAI protocol was created in 1999 was to solve
this problem. http://www.openarchives.org/ All OAI-compliant documents
are interoperable, and can be collectively harvested and jointly searched.

(b) PubMed Central announced that it would become OAI-compliant in 2003:

    "PubMed Central OAI-compliance"
     http://www.ecs.soton.ac.uk/~harnad/Hypermail/Amsci/3010.html

(c) ISI's Web of Knowledge is not yet OAI-compliant, but there is no reason
it cannot become OAI-compliant -- and indeed ISI is collaborating with citeseer
(which Lee Giles hoped would also soon become OAI-compliant:
http://www.ecs.soton.ac.uk/~harnad/Hypermail/Amsci/2332.html ), and may in
the future also collaborate with citebase,
which is already full OAI-compliant: http://citebase.eprints.org/

(d) Even before or without OAI-compliance, there is no reason why all the Open
Access (OA) papers cannot be jointly indexed by an indexing service, along with
non-OAI papers: Elsevier's Scirus http://www.scirus.com/srsapp/ already does this,
and Elsevier's Scopus http://www.scopus.com/scopus/standard/login.url will
undoubtedly do so too.

So, as you see, there is no problem. It is just a matter of coverage. If Elsevier
can cover the growing OA corpus, Pubmed and ISI can certainly do so too. And then
their users will have seamless access to both OA and non-OA contents jointly.
Whatever contents PubMed harvests, it covers; moreover, if PubMed is
OAI-compliant, its own contents can be harvested and covered, by other
meta-engines.

Moreover, as also discussed in this Forum lately, google and yahoo are also 
taking steps to make themselves more useful in this regard, with special
arrangements being made for covering the OA literature.

No. The sensible thing is for PubMed (like scirus and scopus and eventually ISI
too) to harvest the metadata from OAIster and other OA sources such as
http://archives.eprints.org/eprints.php 
and thereby to provide the kind of comprehensive coverage that will be most
helpful to its users. (CogPrints is of course covered by OAIster, Scirus, etc.
and google even covers the papers on author's home websites -- though
OAI-compliance would help the visibility and harvestability of those papers!)

There is indeed. See above.

So the real problem is not how to cover and search the proportion of
papers for which self-archived OA versions exist, but how to fast-forward
us to providing OA for 100% of our papers!

For this I can only requote Swan & Brown (2004) who 

    "asked authors to say how they would feel if their employer or funding
    body required them to deposit copies of their published articles in
    one or more... repositories. The vast majority... said they would
    do so willingly."
