I have an N810 and "ported" and modified Comix for it -- it's hildonized and it runs.

It can kindly be called resource intensive -- opening a new file takes 5-15 seconds, and I occasionally get notified that it's stopped responding, although it recovers. Aside from the start up time, though, it's everything I wanted in a manga reader and the image quality is better than using the built-in image reader. Anyway, if anyone else would like to use it, I packaged it up and made a repository:


It should work for OS2008 on both N800 and N810s; I no longer have a 2007 device.
