|I went ahead and coded pv2flag - it's a program that flags the location of known-patchable areas in the firmware, and works across all of the firmware revisions I've tested it on. It flags locations based on the CRC checksum of the local byte range, and thus contains 0% firmware. New known-patchable areas are easily added to a resource file.|
It's a command line app, and should compile under any modern OS with an ANSI C compiler and a libc. (Linux, HP-UX and Windows tested so far) A Windows binary is included.
