i have had one experience with trek's aftersales, a few years back. i had a trek that i used to race xc on sundays and dirt jumping on the rest of the time, prior to there being dedicated gnarl bikes and parts available. unsurprisingly, i eventually cracked the frame right through the down tube/headtube interface. a couple of weeks later, one brand new frame free of charge, no questions asked (probably for the best!).
Right lets get this straight. It's ok for you to use a xc bike as a jump bike brake the frame in half due to misuse and managed to get a new frame by not being totally honest?
on the evidence, i suppose so. as a skint 17 year old i was pretty pleased with that outcome. and it's "break", by the way.
