are you really sure 0xd4 is sent before any other
keyboard event (key press and/or release) ? I mean
that
if you press alt + sysrq, and hold them down, do the
0x54 code repeat alone, doesn't it repeat, or do the
0x54/0xd4 codes do flip-flop ?

no, hopefully there are other keys such as shift, caps
lock, numlock. What about Alt+CapsLock ? this
combination is never used anywhere. Capslock sends
0x3a.
also try to use Right Alt (Alt GR) instead of left
alt.
Mine generates E0 38 instead of 38 alone, and is fully
compatible with SysRQ. Perhaps your SYSRQ will stop
sending release codes with this key pressed.

try it inside vmware on a boot floppy with just your
kernel, it works really fine, but you'll never see how
your keyboard behaves until you give it a real run ;-)
