I was trying to replace that 2.5mm by 3.5mm and found this one:

http://cz.farnell.com/multicomp/mj4435-r/socket-3-5mm-jack-smd-3pole/dp/1638670?Ntt=1638670

which seems to fit there (I was playing with the dead motherboard you've
sent me). But it has no switching contact for jack presence detection.
