He says he was probably remembering wrong and that it was actually just a high end Duo.
Also, I got the E6500, flashed the latest BIOS, and installed the QX9300 and I have an issue. In the BIOS it shows 4 cores, but in Windows I only have 2 cores and half the cache available. The E6500 never officially shipped with a Core 2 Quad, but it's sister laptop the Precision M4400 did, and is identical aside from better GPU options.

I told you
Because the other 2 cores are disabled. As I have just found out, there are 2 versions of E6500. With built-in Intel graphics and the other one hosts Nvidia (which is M4400 sister board as you are saying). The former board has GTLREF_2 not connected, so only duals can work. In the latter case, quads should work fine.
So I guess your board has just Intel graphics. If so, you will have to do the mod.
