Thanks, what an obtuse interface, I never would have figured that out.
Seems racy as all hell to me but nevermind ;-)

Looking at ts219-setup.c "QNAP TS-119/TS-219":
MPP44_GPIO, /* Board ID: 0: TS-11x, 1: TS-21x */
But I'm not sure if x is always "9" or if this board file also supports
110, 112 etc. I suspect it does support the others.
The 109 is the Orion based on, arch/arm/mach-orion5x/ts209-setup.c
doesn't seem to declare a GPIO to distinguish 109 from 209.
