Norwich's late winner against Derby means Rangers need another point to rubber-stamp their promotion back to the top flight for the first time in 15 years. But Cardiff would also have to engineer a 13-goal swing to deny Neil Warnock the seventh promotion of his managerial career.
Warnock's long-time leaders have stuttered on the home straight and David Amoo's equaliser made it a defeat and three draws from their last five outings.
But the fans still sprinted on to the pitch as a packed Loftus Road partied in the spring sunshine while even Flavio Briatore, no longer the Rangers chairman but still a shareholder, put in a rare appearance to join the knees-up.
Rangers made the breakthrough, with Adel Taarabt unsurprisingly the architect. The Moroccan threw one of his occasional tantrums and asked to be substituted when these sides met earlier this season. But he silenced the taunts of the away fans with a superb through-ball to the turbo-charged Wayne Routledge, who roared past the Hull defence before slotting his fifth goal of the campaign past Matt Duke.
But the hosts were stunned with nine minutes remaining when substitute Amoo latched on to Hope Akpan's ball over the top, steadied himself and crashed a superb 20-yarder past Paddy Kenny to deny the keeper a 25th clean sheet of the season.
