Huge Mouse Lag on Lenovo X60

[robojo]

Hi, I'm attempting to install Snow Leopard (10.6.0) on a Lenovo X60 Tablet.

 

I've made a patched USB installer from the retail disk and the EP45UD3P patcher, with ApplePS2Controller.kext added to extras. This installed OS X like a dream.

 

I'm now trying to get the tablet up and running with TabletMagic, however it comes up as "No Tablet Found". I think this may have something to do with the southbridge as other peripherals are also responding oddly.

 

Plugging a USB mouse in shows that the USB seems to be polled only once every two seconds. When moving the mouse there is a two second (approx) lag, then the position is updated once. Two more seconds must be waited before the position is next updated. USB keyboards respond equally slowly. When a key is pressed there is a two second delay, then the text onscreen is updated with seven of the pressed character. The laptop's keyboard and trackpoint have no lag and the general speed of the laptop is no slower than expected on the 1.5GHz Core2Duo.

 

This issue is specific to OS X, both Ubuntu Narwhal and XP tablet 2005 read peripheral inputs correctly.

 

 

 

 

Has anyone else experienced this or similar?

 

I have a Lenovo X60 6363P3M with a 1.5GHz Core2Duo with 2GB RAM, if any other details are relevant ask and I'll post them. Thanks!
