How can I visually identify which board revision I have?
This question asks about using /proc/cpuinfo to identify the revision of the board I have.
Are there any visual characteristics that differentiate between the different board revisions?

How can I identify from command line which board revision I have?
I just ran
cat /proc/cpuinfo
on my board. I get "Revision : 1000002". I've failed to find any mention of which version of the board this is.
Any help?

How does a program check whether it's running on a 512MB RPi?
Do the 512MB RPI's have a different board revision?
ie, can you just look at the revision in /proc/cpuinfo to determine if you have
a 512MB RPi?
Otherwise what's the easiest way to check?

What are the software implication of changes in Model B, rev 2.0?
As described in http://www.raspberrypi.org/archives/1929, there are various changes. Does this affect software that isn't using I2C or the new GPIO signals? I'm assuming I wouldn't be using the emulator or JTAG.
