DLL naming problem on the sigmarion 3

I've got an annoying problem I'm having trouble getting around. I've got a driver that is trying to load a DLL from ROM called SDBus.dll. Well, on the sig3 this file is called SDBusDriver.dll instead. Normally I would just use execheck to rewrite the driver name but the real one is longer so I can't do that. I thought about pulling the dll from ROM and renaming it but after going to the trouble of extracting the sig3 ROM I realized pulling a particular DLL out of there may be very very challenging. I looked around in the registry and there isn't a place to specify that the driver should use SDBusDriver.dll instead of SDBus.dll, it's hard coded into the DLL.

Any ideas how to proceed here?
