Ignoring previously revisioned files

I've been looking for a while and haven't found any reference to this.
I have some files that were at one time manually edited, but I now
generate these files during our build process. Without loosing the
revision history in subversion is it possible to svn:ignore these, now
generated, files? I've tried adding them individually and with a
wildcard into the svn:ignore property but they still come up as deleted
(non-revisioned files are being ignored, so I'm doing that correctly).
Is there a way to do this?

This seems like a common enough need that I would expect there to be a
way to handle it. Am I just missing it? Thanks for any suggestions.
