I have not tried this, but the status register on the 68K architecture can
change depending on whether you are running in User or Supervisor modes.
If you are in User mode then you do not have access to the interrupt part
of the SR.
I do not know if the Palm forces client code to run in user mode, but it
would certainly be reasonable to do so.
