I have done this and can tell you it is due to the programming on the console eprom.

I am a bit of a electronics nerd and used an eprom programmer and a 8 pin clip to copy off the old programming and copy the programming from the 996 cluster onto the boxster chip. the voltmeter works perfectly now, but the fuel gauge is very slightly low. I am planning on doing some experimentation soon to find out what to change on the programming to get it working.

If you want to ship both clusters to me I am happy to copy one to the other for you. I can update mileage as well. Not sure if I can test it as I have a 97 with the old style connectors. I'm also happy to point you in the direction of what to buy (around $250 (Edit - just found a cheap chinese version on ebay for $47)) and how to do it if you want a DIY solution.

PM me for details.
