It should fire (i.e. sync only), but there will be no flash metering - meaning the camera will not take the flash output into account when calculating the exposure.
Never used Nikon Speedlights, so can't comment on what the actual behaviour will be like. If the SB25 has it's own thyristor then you can use it on your 20D.
But no TTL, then sibeh siong right? Need to make sure all the settings on the flash are correct.. I already have problems using a SB24 with my D70s, SB26 still ok.. Don't say using different brand of flash and DSLR together, even worse?

well..photography had gotten a lot easier already. Last time, there were not autofocus, no auto film winding, flashes were huge and mounted at the side, no build in light meter.
I think i can live with the need to adjust aperture on the flash if it gives me good pics.
