Comment (by pulkomandy):
So, after checking more closely:
- Active multiplexing is not supported *by the controller*. I misread that
as not supported by Haiku. It is irrelevant in this case.
- From the logs, I see that the synaptics touchpad is wired to the PS/2
port, and its passthrough port is used for the trackpoint.
In the "both" and "trackpoint" cases:
{{{
2071 KERN: ps2: devfs_publish_device input/touchpad/ps2/synaptics_0,
status = 0x00000000
2121 KERN: ps2: devfs_publish_device input/mouse/ps2/ibm_trackpoint_0,
status = 0x00000000
}}}
In the "none" and "trackpad" cases:
{{{
2070 KERN: ps2: devfs_publish_device input/touchpad/ps2/synaptics_0,
status = 0x00000000
2123 KERN: ps2: devfs_publish_device
input/mouse/ps2/synaptics_passthrough, status = 0xffffffff
}}}
So, the trackpoint enabling/disabling in the BIOS seems to work, but the
trackpad option doesn't. I don't know what it is supposed to do, but the
trackpad is still there, and we cannot pretend that it isn't, right?
So it seems the main problem here (touchpad not working) is a problem of
the BIOS failing to disabling it, and there isn't much we can do about
that.
