Hello, I'm using Sony VAIO VPCEB1Z1E with this touchpad:
May 11 21:38:12 localhost kernel[0]: ApplePS2ALPSGlidePoint::identify: Found ALPS Device with ID E7=0x73 0x02 0x64, EC=0x88 0x07 0x8a
May 11 21:38:12 localhost kernel[0]: ApplePS2ALPSGlidePoint EC Report: { 0x88, 0x07, 0x8a }
When I try to use your kext I get KP on VoodooPS2Trackpad. All previous versions of PS2 were removed, aslo cache was rebuilt. Can you try to solve this? I'd like to use fresh kext (this).
