. Well, if you don't have access to some crazy hardware flasher then you probably want to attack HP's RSA-SHA1 validation code for the DxE image. As far as I can tell, it's the weakest link and it is actually all you would need since whitelist and the bios setup utility is stored there [bios setup utility = the one that opens when you hit F10 at boot]! However, with the lastest bios releases HP has "strengthened" that link (no idea if they are reading the boards or not, or maybe they got a lead from the people who bricked their laptops and then returned it). About the keys: I'm not aware of any leaked private keys. Maybe some of the Russian or Chinese folks know more but it's difficult to contact these communities. I'm still looking though, because once we got one, we can complete hewprsa and integrate it into AndyP's tool. Another possiblity would be: adding support for the dv6's ec to flashrom. However without a laptop "donated" to science to some of the flashrom gurus I don't think it will happen in the near future.
