sorry I can't help with this, but as a numpy evangelist...

this creates and unneeded copy, but you can do:

temp_out *= -1

to do it in-place. (that's certainly work with numpy, but I'm pretty 
sure it's supported in Numeric as well)

One other thought is to use pyTables to get your HDF data, and write the 
geotiffs with GDAL:

Sorry I couldn't be of more help.
