As has been mentioned by others, the Palm M105, the TRG and the Visors are probably your best bet.
Not Palm OS, but a Psion of some sort (keyboard included of course) would be an alternative option.
Not aware of a modern Pocket PC/Windows CE device that ran on regular batteries, the HP I have is donkeys years old.
The Plam M105 used the 'universal connector' which means that modern keyboards should work with it, assuming they have drivers for which ever version of Palm OS the 105 has. One downside of the 100 series was that they weren't flash upgradable.
Very few (probably read none) modern PDAs use regular batteries simply because they all have colour screens and they just eat batteries. That's why all the new ones are rechargable.
