Hi, you can easily check the version of OS you're running on your 
tablet. Using menu go to the 'Control panel', then choose 'Device' 
section and inside the new opened window change to the tab 'About 
product'. Here you are!
For instance, on my tablet I have there:

Nokia 770 Internet Tablet
Internet Tablet OS 2006 edition (that is the final OS 2006 release)
Version: 1.2006.26-8
WLAN MAC address ...
Bluetooth address ...

So if you still have OS 2005 then binaries compiled with maemo 2.0 would 
definitely not work on the tablet.

Cheers,
Andrey
