Probably just broken.

The INI settings do get read:
https://github.com/LinuxCNC/linuxcnc/blob/2.9/src/emc/ini/inispindle.cc#L65

And fed into the spindle settings:
https://github.com/LinuxCNC/linuxcnc/blob/2.9/src/emc/ini/inispindle.cc#L100

And set here: 
https://github.com/LinuxCNC/linuxcnc/blob/2.9/src/emc/motion/command.c#L1555

And the code here (setting the HAL pin values) appears to limit the velocity:
https://github.com/LinuxCNC/linuxcnc/blob/2.9/src/emc/motion/control.c#L1908

(Though it looks like I might have got my > and < the wrong way round
for negative spindle speeds.
Can someone else check that I am not double-thinking this?)
