Oracle insists on a "support identifier" and matching company name before downloading anything from them. There is no apparent way to get this, so it seems that they effectively block further support for old Sun hardware unless you're willing to pay to be an Oracle hardware reseller. :-(
The easiest way to get past this problem is to ask around for someone that does have access to the Oracle's support site. Technicians or Engineers working for corporations that have support contracts for Sun/Oracle servers should be able to help you (if they want to!)
