I have a vintage Ritchey, and encountered this issue. It's hard to find stems with a brake cable pass-thru anymore. You can find stems w/o one, so you have to get creative. You can get a headset brake cable hanger, like this:
...or the fork brake bosses may be compatible with a front V-brake which eliminates the cable routing issue. The V-brake uses a different brake lever, so you'd need some dual-purpose levers such as Tecktro offers.
The hanger is the simpler fix if your headset has enough stack height to accommodate it.
