That error in logcat is normal. Android just complains that it can't send the 
touch boost magic packet to the stock mpdecision binary, which is not running. 
We don't need that since it's all handled in kernel by my mpdecision. I could 
patch the powerhal to remove the sending of said packet, but that would 
interfere with other kernels. So I keep it.

To the wakeup lag:
I don't experience it on stock ROM. Ever.
Are you sure that you didn't trigger the bug report feature when waking it up? 
Its hardcoded into the android ramdisk as a volume key combination. A lag then 
would be normal and I have triggered it multiple times when taking my phone out 
of it's pocket.
