I just read about the typical registers used for
calls. Can it be that we have to save registers r14-r31?
Is there a cheap way to push/pop them all?

If so, the code would probably look like this:

+slp_switch(void)
+{
+ 
register int *stackref, stsizediff;
---> add asm code here that saves registers to the stack
+ 
__asm__ ("mr %0, r1" : "=g" (stackref) : );
+ 
SLP_SAVE_STATE(stackref, stsizediff);
+ 
__asm__ ("
+ 
	mr r11, %0
+ 
	add r1, r1, r11
+ 
	add r30, r30, r11"
+ 
	: /* no outputs */
+ 
	: "g" (stsizediff)
+ 
	: "r11"
+ 
	);
+ 
SLP_RESTORE_STATE();
---> add asm code here that restores registers from the stack
+}

Hope this works - ciao - chris
