I've found a method to make programs resident :
    just write your TSR at address $120 : that's the start of the stack.

So here is an example for the ti-92 : it locks the hand+2nd+on reset.
Hope it will be useful :o)
(Programs must be as little as possible -> max 4Ko)

                    reset.asm :

 xdef _main
 xdef _comment

UserStack equ $120

_main
 movea.l #UserStack,a1
 move.w #$0700,d0
 trap #1
 move.l $78,fin+2

 movea.l #int,a0
.loop
 move.b (a0)+,(a1)+
 cmpa.l #int_end,a0
 bne .loop

 bclr.b #2,$600001
 move.l #UserStack,$78
 bset.b #2,$600001
 trap #1
 rts

int
 move.w #%1111111111111110,$600018
 nop
 nop
 nop
 nop
 nop
 nop
 btst.b #3,$60001B si touche lock enfoncée
 bne fin  alors on sort de l'interruption

 rte

fin
 jmp ($0).l
int_end

_comment dc.b "Reset BloKer (c) LoVePaRaD",0
 END
