I found it! :)
It has to do with the UNICODE translation code, in SDL_dibevents.c, in the
'#ifdef NO_GETKEYBOARDSTATE' block in DIB_HandleMessage(). The error
handling is a little... aggressive. If it can't translate from unicode, it
wipes out the virtual keycode.

The value returned by \fBSDL_JoystickGetAxis\fP is a signed integer (-32768 to 32768) representing the current position of the \fBaxis\fR, it maybe necessary to impose certain tolerances on these values to account for jitter\&. It is worth noting that some joysticks use axes 2 and 3 for extra buttons\&. .SH "RETURN VALUE" .PP Returns a 16-bit signed integer representing the current position of the \fBaxis\fR\&. .SH "EXAMPLES" .PP .PP .nf \f(CWSint16 x_move, y_move; SDL_Joystick *joy1; \&. \&. x_move=SDL_JoystickGetAxis(joy1, 0); y_move=SDL_JoystickGetAxis(joy1, 1);\fR .fi .PP .SH "SEE ALSO" .PP \fI\fBSDL_JoystickNumAxes\fP\fR ...\" created by instant / docbook-to-man, Tue 11 Sep 2001, 23:00
