jrozes@thorium:/usr/src/sys/compile/THORIUM i386
>Description:
The ALPS GlidePoint device found in the Sony Z505 is not correctly
detected during bootup. It is instead detected as a generic ps/2
mouse, which does not support the 'tap' feature the GlidePoint is
capable of. This is due to the device returning a different value
than expected in the first status byte, as checked in enable_aglide()
in sys/i386/isa/psm.c.
>How-To-Repeat:
Boot any 3.2-STABLE kernel with a psm device configured on a Sony
Z505-series laptop. Mouse will be detected as ps/2 generic.
>Fix:
Don't know if this is really the right way to do it, but here's a
diff that checks for the old status value as well as the one returned
by the GlidePoint in the Sony Z505.
