Haxby, I couldn't do a better job describing IGBT's than these 2 application notes I will link to:
App note 1)
Infineon-EiceDRIVER-Gate_resistor_for_power_devices-AN-v01_00-EN.pdf
App Note 2)
AN-7003_Gate_Resistor-Principles_and_Applications_rev00.pdf
Warp and Solar Mike have a lot more experience with IGBT's so I would rely on their help and the App notes to find your solution.
As you will see from the App notes larger gate resistors than MOSFET's use are common.
The problem and solutions we are discussing here are less relevant than with IGBTs they are a bit different when it comes to problems, causes and solutions.
