The radeon driver sets the dpi values to (75,75) even though it correctly detect my panel's dimensions (338x270mm) and resolution (1280x1024), which should result in a dpi value of about 96x96.

Can you attach the output of xdpyinfo?
closing due to lack of response. I think the DPI should be correct; the the line in the log is misleading, but randr does the right thing. Check xdpyinfo.
