Tedz, I got scared when I first read the header "compact flash", I thought we were about to start a discussion about midget perverts in raincoats. Whew, glad I was wrong! My Olympus uses "Smart Media Cards", and doesn't have "raw" image capabilities, however it does shoot hi res tiff, and they use up about the same space as raw 8-12 meg, so the numbers being thrown around seem to be right. I don't have any 256 cards but I have several 128's and the numbers seem to average out to what everybody is getting.
