Seems to do what I want, IOW, when I update the kernel via Update Manager, the module is recompiled as needed. Although it didn't do the job the first time I updated the kernel. For some reason, my module was not recompiled. I don't know what the problem was. I made some more tweaks to my dkms.conf file, repeated key DKMS commands, and it seemed to do the trick, because the module was recompiled on the next kernel update. I think I've only had one kernel update since that time, so I'm not 100% sure I've got it right.

Well, the contents of the .tgz is 28K bytes unzipped, so I've put the .tgz on my web server here:
http://www.hbuus.com/ir-keymap-0.1.tgz

You need to untar it (or put your own stuff) under /usr/src and then use the dkms command to add, build and install, IIRC. It's been a while, so I'd have to re-read the man page to give better instructions. I have confidence you and Christoper can figure that out <vbg>. If you get stuck, let me know, and I'll try to help.

FWIW, I used the Ubuntu packaged nvidia driver installed on my system as a template for the dkms.conf and Makefiles. So, if you're using a newer nvidia driver than what Ubuntu provides in any of their repos, I suggest using one of their source nvidia packages as a template.

HTH,
