Sweden didn't have any problems with "y2gay", noone from the tax authority complained about massive changes there.
However, the whole transsexual/intersex phenomenon is causing more issues. Basically, gender is encoded in your ID number, and stored in the census database, so people who change gender won't get a new ID number, so there will be a discrepancy between their number and the (correct) database value, but some systems don't bother checking the database, they just infer it from the number, and choke when the gender is "wrong" for something, usually systems around registering parents.
I think the long-term solution will be to just stop registering the gender of people, and not make any system care about it anymore, thereby reflecting the current cultural norm. :-)

You do, in fact, get a new personal identification number when undergoing gender reassignment surgery.
