I was just trying to install these .debs on Ubuntu 12.04 at Beaglebone Black, but it doesn't work. Basically ubuntu repos for ARM have libboost version only 1.48 available, while these debs require 1.49. It probably can be compiled from sources, but that's not as simple as just installing some ready packages and also will probably take much time on a weak ARM CPU.
I might be able to decrease the requirements in the Debian control file, but I would need somebody to confirm whether 1.48 and 1.49 would be compatible and whether there are likely to be any linking issues.
Trying Debian Wheezy on the same hardware.
That should work as it's what the debs were designed for. You still could well struggle with only 512 MB RAM though (at least for downloading the blockchain).
