If boot polishers would actually do some research that would be something wouldn't it?
Yaroslav Trofimov wrote a detailed book about what happened in 2008. His is in every sense an AUTHORITY on explaining the history behind the incident. From a Q&A done about his research, this is how he summarized the support given to the Saudis at the time:

Absolutely no mention of Pakistani involvement during the event.
The only record of Pakistani involvement is in Musharraf's memoirs (which wikipedia references too). You won't find any mention of Pakistan in proper sources.
@Sage I hope this helps in your case too.
