aps0 at isa? port 0x1600
apsdriver provides support for several sensors found in some ThinkPad laptops.
The sensors currently exposed via the sysctl(8) interface are:
||Unknown||Weighted X Acceleration?|
||Unknown||Weighted Y Acceleration?|
apsdriver first appeared in OpenBSD 3.8.
apsdriver was written by Jonathan Gray <firstname.lastname@example.org>.
apsdriver does not yet maintain state and subsequently does not take evasive action when it thinks the hard drive is in danger.
The Y axis on X40 and possibly other models seems to be inverted. It is unknown how to distinguish between different versions of the accelerometer to compensate for this in the driver at this time.
As IBM provides no documentation, it is not known what all the available sensors are used for.
