I think that the most reasonable and light-weight way to do that would be to detect the underlying OS, and parse the output of some command line commands. (for example, uname and the contents of the file /proc/meminfo on Linux)

Java graphics performance for games has been shown to come down to the drivers that the card uses, on occasions, so I doubt any of this information will be of much use to discover if the game will run OK.

It would be more useful to run a test on a fixed size rendering surface and count how many FPS can be drawn.
