Hi, http://kanotix.com/files/debian/acerhk/ That package was made by your's truly for the Kanotix project.Although I am not officially involved with debian, I currently co-maintain some other module packages (spca5xx and madwifi) on alioth. If a developer would like to sponsor and co-maintain this in a similar fashion I'd be more than happy to help out.
acer-acpi module may also be of interest. (for amd64 users) Thanks, Kel.
