A tool has been released on ps3hax.net to read the PS3 NAND chip with the Infectus chip:

This tool is used to interleave, then byteswaps both dumps of the PS3 NAND.
Upon completion, it creates a 'user readable' file.

This file is then scanned by the tool, and the flash files are extracted to a folder.
This folder is named PS3Nand-XXX.XXXX, where XXX.XXXX is the SDK Version magic in the flash (usually the version number of the firmware)

.B .A usually works, however in some cases .A .B order is required.
The tool was made by mainman, assisted by the PS3News.com Developers!
