Release 0.1.9 Edit
From Trammell Hudson, Nov 28 2010:
I have been neglectful of my favorite camera these past few months and left it running the older 2.0.4 Canon firmware. Today I spent the afternon locating the necessary symbols (thanks, patchdiff2!) and have built a version that boots on the 5D Mark II with 2.0.8.
Attached is a version for folks to test. I put it through some tests and the few things I tried seemed to work (autoboot, MBR writing, zebras, int/ext mic switching, etc). I also fixed (?) a bug in the bmp_load() code: by reading into an uncacheable region of memory it seems to never get the bad results from the read.
Please give it a go and let me know if there are any outstanding issues. Once we have it a stable we should make this one generally available since all the new cameras have 2.0.8 pre-installed.
FYI: if you have a camera with a serial console, there does appear to be a password on the port now.
