The Magic Lantern firmware for the 5D Mark II is available for public beta! There are still some very rough edges, but it should be usable for wide-spread testing. In the 0.1.3 version there are:
- Onscreen stereo audio meters
- Full-time cropmarks
- Zebra stripes for overexposed regions
- Fixed audio gain (+10 dB analog, +12 dB digital) with -NO AGC-
- Live headphone monitoring on A/V jack (without disabling LCD)
- printf() to the bitmap display
- GUI event viewer (press Picture Style button)
The button remapping was having problems, so it has been pulled out for now.

FAQ for most questions regarding the software.
Keep in mind there are
no warranties and no guarantees, and if it breaks your camera you get to keep both pieces.
