If I'm correct, those figures are the numbers of pictures that can be recorded consecutively to a sandisk 256M card before the available buffer is used up. It's a function of the camera's buffer size and transfer (to card) speed. IOW: use a slower card, and you get (much) worse results.

I just looked at the buffering specs again. To me it reads: 4-5 NEF or 12-20 JPG. What is interesting is that it seems to have a very robust compact flash interface (developed from the D2H?). Hence, if you shoot at a smaller filesize (such as the large+normal), on a very fast card (Sandisk ultra II), you would be able to continue right on until you fill up the card (hence the 144 shots claim on a 256M card by Nikon). If you use NEF exclusively though, you will still benefit from the speed. The difference would be like upgrading your computer with a very fast harddisk.
I looked up the max throughput of the D2H and its at 4.5M (as measured by DPReview with ultra II). It seems the D70 should easily double the throughput of a digital rebel!
I think Nikon should run a joint promotion with Sandisk, congratulating each other for their speedy products .
