Well, dpi number does not matter at all - important is the absolute number of pixels you render. On which area they are spread out can easily be setup in Photoshop. And when you do 300 dpi it means that you need it for print and for that you have to change color mode anyway to CMYK.

I know, when you set it up with 300 dpi it should "keep" them. But as long as it can be changed sooo easily i would say E-on should concentrate on more important issues.
