I have always export in metric now (since I wrote the patch to allow it ;-)). 
The metric Gerber and drill files have the same resolution, that's a very
good reason to use the metric export option (not the default for compatibility
reasons).

I don't know if there is an official release with this option, I am 
almost always at the bleeding edge for gEDA and PCB, compiling from 
a git repository. If you export from the GUI, there should be a metric
checkbox in the export dialog, if you use a command line, add --metric
to the options.

	Regards,
