To cover a whole wall, 150 DPI is gross overkill. Most of the time, you 
only need half as much or even less, something in the 50 to 75 DPI 
range. Anyway, you won't usualy look at it from less than a few feet... 
You can then use interpolation and error diffusion type dithering if you 
wish.
It can make an image of about 640 by 480 printed at 1400 DPI, 8" by 6" 
look very smooth with absolutely no pixellisation. I know, I've done it 
a few times with excellent results.

You can render in pieces, or tiles. Use an orthographic camera, 
translate it as needed and render several smaller parts. It can be done 
automaticaly using animation.
