Basic analysis: runs VxWorks.
Thorough analysis: I have been unable to decrypt the main firmware payload, as for any other model. No help there. It does have the strings EnableBootDisk and DisableBootDisk, so I think it's possible to modify the flasher to execute EnableBootDisk, after which booting with AUTOEXEC.BIN should work. I guess that's as useful as it gets.

@DataGhost
bootloader (400d\40d) have code for read\write to flash. It is probably possible to use for making udumper for EOS. But I could not analyse a code for write - only for createfile.

Yeah, that's also possible but AUTOEXEC.BIN should be able to handle that as well :) might be a lot easier. I guess that's the way everyone will want to go anyway.

Tell me if i have understood right, running code in eos camera is not as easy as in P&S, and it requires to write a "patched" firmware in the camera rom?

Something like that. By the way, movie mode on the 450D is possible for anyone who was wondering. I recorded a movie on my 40D yesterday :)

I've seen it!!!! AAAHHHHH!!! It's crazy!!! Can't believe it!!
A little step for a man, a big step for the mankind :D
How is that you can crack/hack whatever thing you own :D
I would have bought a 40d if I only had known that you had it :) (i've been lucky with S5, i could have been lucky this time too).

i'd like to see (for the 40D) a hack that allows me to view different ratios in the viewfinder 9instead of a matting screen) or at least via liveview.
So, instead of the default 3:4 ratio for example, i'd like to see 5:4 (for standard portrait prints as an example) rather than how much spaceto leave around the subject.
