Have you tried poking into the following repositories for a possible fix:

http://arago-project.org/git/projects/?p=linux-omap3.git;a=shortlog;h=refs/heads/ti81xx-master
http://arago-project.org/git/projects/?p=linux-dvr-rdk-dm81xx.git;a=summary
http://arago-project.org/git/projects/?p=linux-ipnc-rdk-dm81xx.git;a=summary

There are some product-specific forks around TI81x which I don't have any 
visibility into and hence I can't support it in meta-ti... :(
