10.1 server geoprocessing tools 64 bit fails if dependent on 32 bit dll?

as ArcGIS for Server 10.1 is now completely 64 bit, I think some older custom geoprocessing services developed with C# may not work by simply re-compiling them for 10.1. When a DLL is compiled to 64 bit, I can run the gp tool in ArcCatalog and publish it to the server (this is in a32 bit environment). But when the DLL is dependent on a 32 bit DLL like LOG4NET, the tool run will fail on AGS with "tool not valid" on the first time a statement of the dependent 32 bit DLL is being executed.

Is this correct?
