Opening qtpfsgui HDR files in CS1 (LogLuv TIFF)

Is it possible to open LogLuv HDR TIFs created with qtpfsgui in CS1?

The help files say: "LogLuv TIFF is the appropriate format for most
cases because it stores the hdr data in a reasonable amount of space
(i.e. file size). Even if it is a 16 bit format, it can store floating
point data.
The Float TIFF format has to be used only if you want to load your tiff
in another application that cannot open the LogLuv format."

The float format is 32 bit and I'm pretty sure PS can't handle that...
well I tried & it comes in with totally washed out highlights I can't
see anything in: http://en.wikipedia.org/wiki/Logluv_TIFF

CS2 and CS3 are the only versions of Photoshop that can handle 32-bit
images. Though I don't know if it supports the flavor of TIFF you are
wanting to use. CS2 is very limited in its 32-bit editing, CS3 is better,
but you still don't have all of the Photoshop tools. Not surprising since
32-bit data isn't really design for certain things.
