Thanks for the analysis, Bryce. I'm attaching a debdiff which implements
that change. I don't see any cases in the code where it would be
appropriate to treat these keysyms differently with a modifier, since
they're all special-purpose hotkeys:
gpm_button_xevent_key (button, XF86XK_PowerOff,
GPM_BUTTON_POWER);
gpm_button_xevent_key (button, XF86XK_Sleep,
GPM_BUTTON_SUSPEND); /* should be configurable */
gpm_button_xevent_key (button, XF86XK_MonBrightnessUp,
GPM_BUTTON_BRIGHT_UP);
gpm_button_xevent_key (button, XF86XK_MonBrightnessDown,
GPM_BUTTON_BRIGHT_DOWN);
gpm_button_xevent_key (button, XF86XK_ScreenSaver,
GPM_BUTTON_LOCK);
gpm_button_xevent_key (button, XF86XK_KbdBrightnessUp,
GPM_BUTTON_KBD_BRIGHT_UP);
gpm_button_xevent_key (button, XF86XK_KbdBrightnessDown,
GPM_BUTTON_KBD_BRIGHT_DOWN);
gpm_button_xevent_key (button, XF86XK_KbdLightOnOff,
GPM_BUTTON_KBD_BRIGHT_TOGGLE);

I will open that one as a separate bug.
