Yeah, you need to adapt to it. I had the same, don't think I realised how much I was using the saddle for sitting down, even for very brief moments on downhills. Just have to learn to ride slightly differently using your legs a bit more to shift your weight around rather than through your arse.
I'd say even a 100mm modern 29er XC bike would be a lot more capable than your rigid 26" inbred.
