Sounds like the NEC 710T is different, here's from dmesg:

CPU: ARM710T [41807101] revision 1 (ARMv4T)
Machine: Psion Windermere NEC ARM710T

I don't remember if I tested the thumb stuff as it's been few years, 
but it's a v4 :)

Yeah, the original Series 5 is CLPS711x. Psion 5MX, Revo, Diamond
Mako and Ericsson MC218 are all based on Psion Windermere architecture,
which uses a NEC 710T.
