That is amazing . . . Imagine if I upgraded to 16GB would the system be able to handle all of it?

PS @rewt Thanks for the great info!!!!!!
4G of very slow RAM, yes. And 16GB should be possible as well. I don't see why you'd need it though - I've never come close to using up the 1G that's setup on there at the moment.

And you may also be able to use swap files instead, which saves wasting all the SD card, e.g:
Code:
dd if=/dev/zero of=/media/mmc1/swap1.img bs=1M count=1024
mkswap /media/mmc1/swap1.img
swapon /media/mmc1/swap1.img
This hangs at swapon on my N900 though, so you may need the card formatted as ext3 instead of FAT32.
