I think I prefer Andreas' approach but with a slight modification - 
change the signature of init_trampoline() from:

static void init_trampoline(void)


static void init_trampoline(ucell *t)

This enables the caller to pass in a pointer to the base of the 
trampoline ucell array, and so should work correctly when compiled as 
part of both bootstrap.c (host target) and the OpenBIOS output target.
