I have a dead tree version of the datasheet here and compared
it to the PSB2161. The internal registers are different. The PSB2160
has less features, so some of the config bits of the PSB2161 aren't
available and common bits are sometimes shifted around.

yes, looks doable. I'm not sure, whether I have the time to it myself,
but I could help people with questions about the PSB2160 config registers
(I'll write the register bits down and put it online during the next days).
