Also, the ssm2033 doesn't have a thermistor on it in the MP4, those are just metal film resistors.
They aren't used for temperature compensation they are used to heat up the chip. The internal heater in the ssm2033 takes too long to heat up, so Korg affixed additional resistors on top of each chip that are driven by the 2sd794s to help speed up the process. It's pretty ingenious really.
What I would suggest if you really want to move the chip is to unsolder the resistor and move it with the chip without removing the resistor from the chip. The thermal conformal coating that Korg used is pretty nice, but once you break the bond, the resistor won't help the chip heat up as well... You can always use thermal compound to help transfer the heat, but i have found that the heating rates are different So you'll have one chip that lags behind the others.
Unless you have to replace an oscillator chip, I would say don't remove that resistor.
