My understanding is that all NiMH batteries start at about 1.4V at full charge, rapidly drop to 1.2V and stay there until they are nearly depleted, when the voltage drops off. It's only the capacity which differs between different NiMH batteries.
If they *were* truly 1.5V they would be better, since they have a greater capacity (1.5V * 2.5 Ah = 3.75 Wh [Watt hours] versus 1.2V * 2.5 = 3 Wh), in addition the GP2X seems to use power more efficiently at that voltage as explained in the post you quoted.
That said these sound like they would be as good as any other batteries, at least!
How can I test this myself? I think I will go today and buy them, test them out, and see if they really are 1.5V (and of course how well they work in the GP2X)
EDIT: Damn asshats..

Click on the picture: it says 1.2V ON THE BATTERY, yet it says 1.5V in the description...
Time to find out how to hook up 3 batteries into it xd
You can use as many batteries as you want in sets of 2, as long as the batteries are wired in parallell Like this:
-battery-battery+
-battery-battery+
-battery-battery+
- 3 volts +
With 3 times the MA rating
But NEVER (-battery-battery-battery-battery+) that's a 6 volt battery
