Interesting mosaic of the heatshield impact crater on the JPL MER site (excerpted below). It certainly looks as though the heatshield hit almost completely flat. I did some very rough calculations on the terminal velocity of the heatshield in Mars' atmosphere (assuming a rough surface area of 10.5 m^2 and a mass of 78 kg)...it looks like the terminal velocity at Mars surface for such an object would be on the order of 120 mph. Didn't make much of a dent, did it? -- but the energy sure bent the hell out of the heatshield!!
