They shouldn't.  DVI/HDMI extenders are basically nothing more than a 
signal amplifier that boosts the signal from STP DVI/HDMI cable to UTP 
CAT5.  The only reason one might give you problems is if it doesn't 
bother passing back the DDC channel, but then depending on your graphics 
driver, you could just feed it your own pre-captured EDID block.
