Dear Lazyweb: Garmin Forerunner 50 linux support

I'm thinking about getting a Garmin Forerunner 50 but am concerned that the ANT USB thing won't work with Linux. I've seen a thread about ANT development drivers going into the kernel, but I haven't found any firsthand experiences. Anyone with any information about it? If it helps, the Garmin Forerunner 405 supposedly uses the same ANT technology.
