I installed linux headers in both my installations (one of which I installed using 6.0.0 cd and other using 6.0.4 cd) using apt-get install and dpkg --list shows same output on both the systems: root@debian:~# dpkg --list |grep headers ii linux-headers-2.6.32-5-686 2.6.32-41squeeze2 Header files for Linux 2.6.32-5-686 ii linux-headers-2.6.32-5-common 2.6.32-41squeeze2 Common header files for Linux 2.6.32-5
When I build driver against the two versions the modinfo output is identical. So I am back to the question: How do I know which driver was built for which version of debian? And even more basic question, how do I know which version of kernel I am running now?

A driver module built using an older version of linux-headers-<kversion> should run against a newer version of linux-image-<kversion>. But the reverse is not generally true. Also, there have been cases where we have accidentally broken compatibility. Ben. -- Ben Hutchings This sentence contradicts itself - no actually it doesn't.
