Thanks for all the responses. 
It seems micromanaging using section attributes and . =0x ... 
is the only way to do this. It's what everyone does, and 
likely the only way if you regard the weirder aspects of 
function calling and optimizations...

PS: the linker knows about assert statements as in 
ASSERT(__StackLimit >= __HeapLimit, "region RAM overflowed with stack")

so a
ASSERT( . >= 0x400, "fconfig overflowed with interrupts")

might be practical.
