I found a solution that works for the Aspire 3810T and, I hope, for others, the merit of an anonymous expert. Please find it at CentOS Issue ID 004246, URL
It writes a brightness level directly to a register of the pci VGA device.
I see this bug was closed. Was another solution already posted, or was it an error? One continues to find more complaints over several Linux distros and Acer computer models.
