SEO / page load times for sections that are display:none;

The new fluid engine is still a bit wonky when it comes to responsive formatting. In response I have been designing entirely different page sections for each screen size (mobile, tablet, desktop) and then just hiding them based on media queries.

My question is... will this method kill my load time and therefore SEO or will display:none prevent them from factoring in?

Please excuse my ignorane. Thanks.

Okay thanks. Any suggestions for how to pursue responsive design in fluid engine?  Just style each element for each screen size using media queries? Nothing simpler?

Fluid Engine has two distinct and separate layouts for mobile and desktop and it should therefore be responsive in this sense of the word. There isn't yet a tablet specific layout so avoiding issues on mid-size screens can be difficult. Media queries don't really help in this respect.
