Hi

I've created a flashable zip that can be used to improve the custom ICS ROMs for the TF101 to work better with the Slider.
You can find it here: [DEV]Slider SL101 Compatibility Pack for TF101 ICS ROMS - xda-developers or here: [DEV]Slider SL101 Compatibility Pack for TF101 ICS ROMS - Asus Transformer Development - RootzWiki

Let me know if everything works!
