RAM doesn't fit?

Question

I have a two-week old Penryn BlackBook. It came with 2GB of RAM, but I immediately ordered a 4GB upgrade kit (This one from Newegg: http://www.newegg.com/Product/Product.aspx?Item=N82E16820134560)
I looked up the memory replacement guide on the Apple website and followed it. I ran into problems, however, when it came to replacing the stick closer to the hard drive (the inner slot, if you will).
The old RAM popped out of the slot just fine. But when it came to putting the new stick it, I encountered much more resistance than I did with the first (outer) slot.
After pushing as hard as I could without feeling like I was going to break something, I thought I had gotten it in far enough. However, the stick was still sticking out of the slot an almost imperceptible amount further than the one of the first slot. Trying to boot them machine produced the three beeps indicating a memory error.
I tried seating the RAM twice like this. After the second try, I broke out a flashlight and tried it inspect the inside of the interior slot. In trying to seat the RAM stick, it almost felt like there was something providing some friction that was preventing it from just snapping into place like the first one; like a piece or rubber or something.
My inspection of the interior slot showed that it was different than the first; there was a piece of clear tape holding down something towards the front of the slot, and what appeared to be a small gray ribbon cable towards the back that heads towards the back of the slot and (slightly) upward.
So I strongly suspect that the ribbon cable (or whatever it is) is preventing me from successfully installing my RAM. This suspicion is reinforced by looking at the two original sticks of RAM that came included with my system (which was a refurbished system, by the way). They are not the same brand, labeling, or configuration; the stick from the outer slot is branded Samsung, and the inner is Hynix. And even more interestingly, the outer Samsung stick has two rows of actual memory chips on them, while the inner Hynix stick only has one.
I don't know whether it's "normal" to get mixed and matched RAM in a refurbished Macbook, but what the characteristics of these two sticks seems to indicate is that when fitting my Macbook with RAM, it was noticed that a stick with more memory chips on it wouldn't fit all the way in, so a stick with fewer chips had to be used.
Just wondering if anyone else out there has encountered this with their Macbooks, and if they have, what luck they've had confronting Apple about it. I am planning to take my Macbook to an Apple store sometime in a few weeks, as the nearest one is almost a 2 hour drive.

Just got back from the "Genius" bar. They genuis told me it was some tape that come loose, so he "fixed" it. He would not install the 2gb ram chip, however because they won't touch 3rd party. So when I got it home and tried again, some problem. I ended up slipping in a playing card to hold the ribbon cable (and tape) down while I pushed the RAM chip in. Worked, but I'm a little worried about the heat of the chip messing up the ram and cable. Seems like a poor design to me, but what do I know?
