Sorry. 
set ::tk::dialog::file::showHiddenBtn 1
set ::tk::dialog::file::showHiddenVar 0
This doesn't work, but the code from my test script does.  I inserted it after the Pd-Extended font hacks, around line 42.

<code>

# begin hack to hide hidden files/folder in tk browser on unix ----------
if {$pd_nt == 0} {
    # load the dialog once, otherwise setting the vars will not work
    catch {tk_getOpenFile -with-invalid-argument}

    # change the environment variables
    namespace eval ::tk::dialog::file {
    variable showHiddenBtn 1
    variable showHiddenVar 0
    }
}
# end hidden files/folder hack ------------------

</code>

Now open/save/saveas dialogs hide hidden files and show the toggle button.  Awesome!  Ok, I assume I might as well open a dev account somewhere are add this as a patch?

Someone else try this in Linux.

You should be able to set that variable in pd.tk and have it work without modifying the other file.  Try just adding 
set ::tk::dialog::file::showHiddenBtn 1
set ::tk::dialog::file::showHiddenVar 0
Somewhere near the top of the pd.tk.

IOhannes, you found the magic bullet (or forum post, that is)!

Awesome, I can confirm this works in a little test script and screenshot.  It's a button to toggle
hidden file display as expected.

according to http://www.groupsrv.com/computers/about266840.html it is 
acutally already built into tk-8.4 but not exposed!
