The old DLL switch to make CorelXARA handle bitmaps larger than 4096 x 4096 was to give Xaradraw.dll a temporary name and rename Xdlarge.dll as Xaradraw.dll. Unfortunately, these files don't exist in X as, presumably, the ability to handle large bitmaps is built in.

If Klaus's solution doesn't work, it's probably at least near the answer. The end result must be a TIF, but that doesn't stop you exporting as a PNG or BMP then converting it to a TIF in X or another program.

P.S. what do you mean by 'any file size' and what are the required pixel dimensions of the TIF?
