To summarize igor's post: "no."

To summarize (something like) Igor's post:

Those !@#$^&*ing BGA-loving !@#$%#$@#$%^ers! Why can't we build this with good ol' PDIPs? Back in the day, I could hack anything I wanted on my kaypro!

Rats! I have already soldered the memory from a 16gb SDHC card in the place of the two gig internal memory and thereby totally obscured the area for the TV hack.

Wait, wait, what?! You have? Can you point me to a location with good instructions on this?

Meh, I was going to do that, but decided I needed the room for the 1080p projector I hacked in instead.

Either your humor is even more subtle than Derek's, or you missed his, I'm afraid. The memory boost is a sight easier than the TV-out mod explained by Igor, but it's getting up there.

I'm still working working on soldering in DirectTV DVB into my N800 so I can have portable TV video capture. I even used a Pringles cantenna as my dish!

Qole: Yes, we're joking.

That reminds me when I did similar "hack" on my Atari 520ST to expand the memory from 512KB to 1Meg... I soldered 16 PDIP memory chips on top of the old ones, bent couple pins up to create two new address lines, and soldered those address lines to the memory controller pins using new wires... I think I had to cut couple tracks on the motherboard as well. It was very exciting to turn on the machine first time to see if it still works... and it did!!!

Oh well... that was about 20 years ago...

I missed his. I don't have an N810, so I don't know how difficult it would be. I just know lots of people do something similar on Linux routers, and it isn't supposed to be brain-surgery-difficult.

Well, I've seen it mentioned (and discussed it) before, but since this thread is already hopelessly derailed, and I'm feeling too lazy to search, and too polite to tell you to, here's the deal:

The N810 uses what's essentially a nanoSD card; it's a tiny little chip, in some sort of surface-mount packaging, that's electrically compatible with SD. It makes it easy to add fixed memory to a SoC with an SD controller (like the OMAP2xxx), and indeed Nokia used it for just that. The only problem is it's soldered on, and being surface-mount, it won't be easy to desolder. It's also fairly close pitch, so don't bet on an easy time soldering up wires to it after you do get the chip off. But that's what you'd have to do.

Honestly, the easy way to remove the 2 GB is to mill the chip away, starting from the top, and going down to the contacts, but most people don't have the equipment, and I'm not sure I have the nerve. After all, that's completely removing your 2GB, and if all goes well, everything's fine. But then you're stuck without it if the soldering proves to be a bit more than you can do. (And it just might be, for me.)

Still, if anyone reading this still wants to give it a shot, the floppy cable idea you linked is one option; a (physically) big option, but possible, and at least doesn't risk the 32GB SDHC immediately, so you can bail of things don't work and keep that asset.

You'll want some uberfine wire-wrapping wire to go from honkin' big ribbon cable to the solder pads, though. And do post pictures, even if you wreck the thing.
