Photogenics HDR 6.0 that you downloaded converts 32 bit per pixel RBGE 
files to 96 bit per pixel floating point format to work on, plus allocates 
an undo buffer and a paint layer, so would prefer to have a little bit 
over 2GB to work on a 300MB RGBE file.  Try increasing your swap file size 
to 3GB or so, and er, put the kettle on.  It does support batch converting 
files if you wanted to convert the whole lot in one go.  There is a new 
version of Photogenics in the works that uses much less RAM, I can let you 
try a Windows beta if you are interested, or a Linux beta will be compiled 
later in the week.
