Also, remember that the bolt goes through a metal sleeve, and even though the tolerances are quite tight, you should ensure you only cut the bolt and not the sleeve as well, or else it'll take ages!

virtually impossible, as the bolt is seized the sleeves are tight against the sub-frame, if you can get the saw between the frame and the sleeve to cut the bolt then it's either already loose or you have splayed the mounting hole which will then need repairing
