auto select payment

Hi! My store only has one payment option: Authorize.net. I don't want the customer to have to deal with "selecting" payment option, since there's only one...just want it auto-selected and move on to inputting CC#.

I found this info, but doesn't look like it's updated to 1.5.1.1.

Can anyone tell me how to do this in 1.5.1.1?

Thanks!
Chris

I am looking for a solution to this as well for version 1.5.1.3

Thank you

I'm looking for this as well for 1.5.2.1 - any updates anyone else knows of since this was posted?
