I have additional information for you. I attempted to roll the drivers back to previous versions. v6.2 still produces BSOD, however the faulting driver is now back to atikmdag.sys:

SYSTEM_THREAD_EXCEPTION_NOT_HANDLED (7e)
This is a very common bugcheck. Usually the exception address pinpoints
the driver/function that caused the problem. Always note this address
as well as the link date of the driver/image that contains this address.
Arguments:
Arg1: ffffffffc0000005, The exception code that was not handled
Arg2: fffff88004e9b165, The address that the exception occurred at
Arg3: fffff88002dd9cc8, Exception Record Address
Arg4: fffff88002dd9520, Context Record Address

Debugging Details:
------------------
EXCEPTION_CODE: (NTSTATUS) 0xc0000005 - The instruction at 0x%08lx referenced memory at 0x%08lx. The memory could not be %s.

Downgrading to driver v6.1 has stopped BSOD from occurring, both in power save and when you tell the system to logoff. v6.2 and v6.3 BSODs occur during power save AND when you tell the system to logoff.
