"Device emulation" ?

I ran into a similar problem when I tried to run PPS CAL tasks on a dual-GPU laptop. With a Mac it's easy, albeit slow; the one in question for me was an HP Pavilion dv6 with a similar Intel chip and an ATi HD5450. Once the GMA was disabled, the computer freaked out. It stopped recognizing that it had a graphics card.

So with your situation, BOINC seems to be recognizing your GPU, right?

As it's fairly new technology, I wouldn't expect BOINC to work perfectly with it just yet. Hence you see "CAL ATi Unknown" on some host pages. OPTIMUS is pretty recent, no? The problems I described were also on a Win7 laptop, but running ATi.

Also, unrelated, but that's a heck of a fast mobile i3!

I still don't quite understand what it means when saying "emulator." I presume you have installed every piece of the CUDA toolkit and all the drivers correctly...so my guess at this juncture is BOINC having its own little issues with recognizing hardware and subsequently getting work for it.

Why? Your nvidia gpu was detected.

I would made the setting that nVidia is ever active.
Pro: boinc recognizes only your nvidia/ati gpu
Con: shorter runtimes because nvidia/ati is ever active

Therefore:
The Querying for a CUDA Device is so different in the OPTIMUS Technology,
see http://developer.download.nvidia.com/compute/cuda/3_2_prod/toolkit/docs/CUDA_Developer_Guide_for_Optimus_Platforms.pdf
page 3

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
I think it would be better the app choose the GPU, than jiggle with profiles.
my two cents.

Okay, i read page 2:

"The beauty of Optimus is that it leverages standard industry protocols and APIs to work. From
relying on standard Microsoft APIs when communicating with the Intel IGP driver, to utilizing the
PCI-Express bus to transfer the GPU’s output to the Intel IGP, there are no proprietary hoops to
jump through NVIDIA."

Sounds for me like OPTIMUS is in the moment only available for the win-platform. IIRC, OPTIMUS based on the same mechanism like SLI. In dependence of the app-name the driver automatically activated/switched SLI/the device. Maybe i find another point of view, after reading the complete pdf-file.
