Apparently KDE still does. At least it does not seem to pay any 
attention to KEY_SUSPEND (nor KEY_SLEEP BTW).

And KDE seems to be important enough customer to not wish to break HAL.

Oh, wait. But even Xorg 1.6.0 interprets KEY_SUSPEND as "hibernate".

KeyPress event, serial 31, synthetic NO, window 0x3e00001,
    root 0xbc, subw 0x0, time 87299792, (81,-11), root:(817,290),
    state 0x0, keycode 213 (keysym 0x1008ffa8, XF86Hibernate), 
same_screen YES,
    XLookupString gives 0 bytes:
    XmbLookupString gives 0 bytes:
    XFilterEvent returns: False

So redefining KEY_SUSPEND is going to break Xorg too (as long as anyone 
is using those keysyms).

Ehh ... actually at least in Toshiba case it was not :) hald Toshiba 
add-on always emitted exactly "suspend" and "hibernate" D-Bus events. 
Not "sleep".
