Currently, treat it exactly as a 53C895A.
53C895A is a 53C810 with more capabilities, so this should work.
However, this lets us test different code paths on Linux, which
don't use lastest features if it detect a 810, or on some OSes
which only support 810 and not 895A (like very old Windows NT
versions).
