It should - if it doesn't, then you did something wrong.

By design - buildrom works on a macro level, not a individual file level.
It uses the existance of the final binary to determine if it needs to rebuild
or not, not the individual .c files.  Thats why the olpcflash-clean target
exists.

No - bootmenu needs 'ESC' to pop up the boot screen.  The keypad worked by
luck because if numlock is off, they issue ESC commands which are enough
to bring up the menu.  I'm not sure where you got the numbers thing.  

You press ESC to get the menu, and arrow keys to highlight the entry, and
enter to select it.  Anything else that works is just plain luck.  The source
code is quite clear on this.
