A little more on it
You can use flasher, linux or jaicrab's preloader (basically anything that flashes the dump)
Jaicrab's Preloader only works correctly on NOR's, you'll have problems with NAND's, or so I've tested (thanks to a friend of mine ) in case you need to compare:https://dl.dropbox.com/u/35197530/flashCEX.7zhttps://dl.dropbox.com/u/35197530/flashDEX.7zhttps://dl.dropbox.com/u/35197530/eid_root_key.bin
PS: If I'm not dead by the next 24 hours, you know where to find me

Note: Don't flash this, this belongs to my console, so I advise you not to flash, this is just for verifying only.
From Squarepusher2: You'll have to go digging for debug eboots though if you intend on playing anything that is not a retail game on your debug PS3. And those are not easily found. I don't think end-users will get much use out of it - for devs it's a totally different story though.
Finally, it also appears as though the newer PS3 SDKs will contain the necessary development tools and login information to access Sony's developer network (NP / SP-INT) as well:
The NP communication passphrase and signature will be provided within the Server Management Tools.
Details: NP communication ID, passphrase, and signature, required for certain PSN communication services, had been provided on the DevNet thread upon the completion of the requested PlayStation Network service configurations.
From 2012/07/05 the NP Communication Passphrase and Signature will be provided within the Server Management Tools.
This change affects all the communication IDs issued after 2012/07/05. It will not be possible to access the NP communication passphrase or signature in the support issued after that date.
Only those users who have initially requested the NP communication services and was provided the files on DevNet thread will have access to the file on the request threads.
Note that the NP communication passphrase and signature are required with NP Matching 2 and Title Small Storage.
