It depends.. If you have only links on your portal site, your users
have to click on the link to get to those sites. If IE6 then drops
cookies, that's just default behavior. If you include third party sites
in frames, it is different. In this case, even first party cookies from
those sites become third party cookies...

They can access the site, but the cookies are blocked. If the access
needs cookies enabled. You could write them an email to encourage them
to implement P3P.

As a mesure of security, the policy-reference file (the file that
indicates which policy applies to which resource) can only contain
URI's relative to the host the file is sitting on. So you can't declare
a policy for a third party. You have to control the host to be able to
set the policy. 

So the only way here is to convince the third party-sites to use P3P.
Otherwise, you would have to set the privacy-level to very low on all
browsers as this way, no cookies are blocked anymore. But this also
means, that the privacy protection is disabled.
