I see. 

DAMN!!! :-(

Do you know a reference to this information? More information?
Are there ARM7M chips pin-compatible with ARM710a perhaps?

Strangely, according to my Acorn ARM assembler manual, UMULL is supported.
I will have to write a macro to emulate it then. I hope GNU as is flexible
enough to support that. If not... I don`t know.
