I gave up and took the long road, did a complete kernel recompile, made 
ALSA and Nvidia too, and I am very happy with my USB stick/player. It 
hotplugs nicely, and to load a mp3 file I just drop it with konqueror.
But I still can't believe that it's not possible to compile a single 
specific kernel module. You can do it with foreign modules (cf. the  
ALSA driver), why shouldn't it be possible with the kernel's own ones?
