I can't really say 90 minutes of power is "reasonable". 2-3 hours, yes. 90? No.
That said, my experience leads me to agree with what everyone is saying in the press: higher size process in making chips == more wattage wasted in heat == more power used in batteries; laptops you gotta replace around every two years. I've had a similar setup, an Asus EeePC 701. That had a 90nm Celeron processor on it; even with it being underlocked to 633MHz, it ran too hot. You could not use the trackpad without burning your fingers, and that was on a table propped up for more airflow. That got 2 hours. I swapped it's Ubuntu running carcass out for an EeePC 900A and got nearly 5 hours on the Atom-based hardware (I now run a N10J, same form factor but Nvidia graphics). Add onto that a Dell Inspiron E1505 which I put Gentoo on, and was able to get 4 hours out of it (and how I discovered PowerTop to boot). I replaced it early last year, bought in late 2006; the inverter/backlight was dimming on me. It's with my father now, who doesn't mind it at all. I haven't gotten your take on if you replace the batteries or not. If you got a new battery for it recently and getting that 90 minutes in Windows with it, then something's wrong in the system. If you're running the original battery, then you gotta get it checked; I really doubt they last more than two-three years (unless you're running Linux on a sealed MacBook Pro).
