XnView (http://www.xnview.com/en/features.html) was recommended a few pages back. It isn't a PS but it can do a lot of basic operations or export in a lossless format to something that can do the PS-ish things.
On Linux, I use the RAW plugin for GIMP. That opens UFRaw (see attached), lets you sort out the options that you want (e.g. white balance) and then exports the lot straight into GIMP for processing. If I really want some PS plugin, then as the Applistas say, "there's a plugin for that"
