Raspberry Pi 512m model ram

So this is interesting, by default ( at least with AdaFruit's occidentalis 0.2, http://learn.adafruit.com/adafruit-raspberry-pi-educational-linux-distro/occidentalis-v0-dot-2 ) I was only seeing the first 256m of the ram.

Looking at the documentation http://elinux.org/RPi_config.txt it looks like a simple modification to /boot/config.txt addressed the issue:

gpu_mem_512=8

pi@raspberrypi ~ $ free -m

             total       used       free     shared    buffers     cached
Mem:           486         56        429          0          9         28
-/+ buffers/cache:         18        467
Swap:           99          0         99

It looks like the kernel actually took 16 meg instead of 8 like I wanted but I'll take it :-> I'm logging in only via ssh so I don't see a reason to waste memory on video output.
