Don't know if it was you, but someone else is thinking the same thing on the Midori-discuss list...
But one of the Project admins, Daniel Quinlan, said "We used DiskOnChip 2000 in our really early development (before Midori, really), but have since dropped it for CompactFlash (IDE), which is much easier to use. You will need a special version of LILO to boot (plilo) and a different block device driver."
But, I'm thinking of the same thing. Did you have any luck?
