As far as I know all the ARM unixes use a contiguous stack - it's just RISC OS that uses the chunked stack I believe. I believe you can always tell by looking at where sl points and seeing if there is a valid chunk descriptor there and then following it's prev pointer to get the previous chunk if there is one.
