You can get your IPDS from a byte reversed version of your flash (dump it from multiman), instructions for getting it are on the PS3 Dev Wiki.
Basically you have to search for the hex string inside your flash and there is 3 values that match your model and region of your PS3 and can be found only once in the dump, this is how I got it the other day and it was very easy.
I can confirm it works as I decrypted some content using it!
Hope it help
