I just updated the PS VITA FW xTractor, changelog is attached below.
The 2.00 version had a problem setting the filenames correctly as the 1.0+ updates have different files than the older ones. Anyway, enjoy...

I think it makes sense that since SKFU says "For now it only works with firmware 00.945.040" he has access to Development material with regards to the Vita, but as far as I can make out isn't this similar to a PUP extractor on the PS3 and will output the contents of the PSV FW data?
Also sounds like Sony aren't taking any risks with regards to exploits from the smallest places and encrypting everything: "Just a short info about the firmware itself, it is not unencrypted like the PS3 ones".
I find it interesting what Foo has said that it will extract 30 files regardless of the input - could just be there is no check for file type in the code or it is just hard coded to output them 30 files and populate them with the relevant data.
If anyone has access to the PSV FW 00.945.040, could they do a side-by-side of the info contained within the output files against something which is PSV unrelated?
I have 2 fond memories of the psp: 1 was when it first got hacked with the "swaploit" and I could play Chrono Trigger via SNES emulator; the second was when Dark_Alex released "popsloader" to run the entire library of ps1 games.
With the Vita, I'm even more optimistic. I bet pcsx2 could run on this thing.
