I am running OZ on a 5600 as well. I have had the sharp ROM, OZ 3.3.5, and zynergy ROMs in various orders. I am currently on zynergy, with the preemptive, overclocked kernel. I see the same stuff in the system info, opie, OZ, etc. I think that is just due to the zynergy rom being a hodge-podge of stuff, as is stated on the zynergy web page.
i dont see the same partition info as you, when i go to system info/storage, i see internal flash pretty low, like 3MB.
how did you get the partition info?
