I've got sound working just about now.

I've also figured out that the config.linux file can be used to put your own keymappings in. So I'll update the data file packages with appropriate settings to allow the keypad etc. to be used to control movement in the game.

Here's the diff if you want to do it now:
34d33
< key 1 000111 480000 ; Nokia keypad up = move forward
42d40
< key 1 000120 470000 ; Nokia + = turn right
48d45
< key 1 000121 520000 ; Nokia - = turn left
53d49
< key 1 000113 4d0000 ; Nokia keypad right = move right
59d54
< key 1 000114 4b0000 ; Nokia keypad left = move left
64d58
< key 1 000112 500000 ; Nokia keypad down = move backward

I've also got rid of that annoying thing where if you just miss a movement button, the inventory screen comes up.

I wasn't going to post a new set of builds until I'd got the stuff ready with running from the menu etc. - but that may take me some time - so if you're keen, let me know and I'll post the latest debs.
