obp update patches

Does anyone know how to obtain patches for updating the obp? I'm trying to update a Sunfire V245 to a later version (4.27 and up) so it can boot from USB drives. Oracle's site is absolutely no help and neither is google. I even have the patch number 140685-02.
I believe the current method is to send Larry a big check and grovel.
Damn the torpedoes, full speed ahead!

There are those who say I'm a bit of a curmudgeon. To them I reply: "GET OFF MY LAWN!"

Eh nevermind on trying to extract the patch. I manged to with Linux and you can't apply the patches unless you boot with the cd. They segfault under normal Solaris 10. I plan on giving this server away soon anyhow.
