Alexander,
Check the Maxim MAX6351-MAX6360 family. The datasheet shows that the:
* MAX6355SYUT-T with open-drain output
* MAX6356SYUT-T with 5V push-pull output
* MAX6357SYUT-T with 3V push-pull output
might work for you, monitoring +3.3V (2.93V threshold), +2.5V (2.19V threshold),
and a third input with a 1.22V threshold at the chip. (Use a resistive divider
to set the actual threshold voltage for this last input.) These chips also have
a manual reset input, which can be very useful for debugging.

I'm using a MAX6355LSUT-T to monitor +5V, +3.3V, and the core voltage to an X86
processor. My first cards are being assembled right now, so early next week I
should know how the beastie really works.
