I think it's possible that the javascript file upload widget is timing out waiting for a response from ikiwiki when uploading the file. Since this is a slow CPU, it might exceed some limit in that code. At this point all I know is that the javascript file upload widget is setting an error flag, which is displayed as \"failed!\" in red. The next step is probably to get a http protocol analizer like firebug and see what if anything is being returned by the ikiwiki.cgi when the attachment is uploaded to it -- it should return some JSON with a `stored_msg` field.
