Have you tried the ImageIO plugin at
http://ij-plugins.sourceforge.net/plugins/imageio/index.html?  It has
been able to open any TIFF that I have come across; however, it has two
hassles:
1) You have to use the Plugins->ImageIO->... menus to open the files
rather than the standard File->Open methods.
2) From a Plugins programming perspective, the FileInfo structure isn't
setup by the ImageIO openers -- thus, for the few plugins that I have
that require access to the underlying file (rather-than/in-addition-to
the rasterized image contents), I am still outta luck!
