You need to read a publishing tutorial on different graphics formats, 
their purposes and intent. I seem to recall a message being posted here 
on this sort of thing --- it might've become a TUG article....

AIUI, GIMP saves a bitmap .eps --- that your image is a 72 dpi bitmap 
is the crux of your problem. _IF_ GIMP has similar capabilities to 
PhotoShop and _IF_ you've created the image entirely using bezier curve 
paths which can be re-rendered at a new resolution _AND_ text objects 
(which are still text and can be re-rendered live) then you could 
re-set the dpi, the image would be rendered at the new resolution and 
it could be made to look decent.


That's not an optimal approach. The file will be large and 
unnecessarily resolution dependent.


you re-draw it using vector illustration program (additional options 
include xfig / jfig and Visio or Dia --- that last is probably your 
best option) it will be resolution-independent and efficient in 
filesize and display time.
