Using Magic Lantern AJ 5.9 and a SanDisk Extreme Pro (90MB/s, UDMA 6) CF card, I was able to continuously record CBR video at 200% bit rate with no stuttering or buffer overflows -- according to the Quicktime info, I'm right in the neighborhood of 64Mbps.
Any of you shooting on 5Ds that are having artifacting issues in post (color correction, greenscreening, etc...), this is the way to go.
Edit: I should probably point out that the card was formatted, as opposed to just deleting existing clips. I've hit stuttering and buffer issues on cards that weren't freshly-formatted before shooting.
