A single 32bpp 4096x4096 texture requires 64MB of card memory. Mipmaps multiply that by 4/3, of course (but reduce the memory bandwidth used at render time, so you want these even though they cost memory). Add in all the other stuff that gets drawn and the framebuffer and you can probably just barely fit this on a 128MB card. At 2m per pixel, that's a 8km square area. A 256MB card might be able to get you 12x12km or so.
