It seems that Linux boots and runs on the co-processor card. What is the

Phi as a co-processor, or even usefully boot and run natively on Xeon Phi?
It attaches to the PCIe bus like a GPU so I imagine there would have
to be a driver for whatever OS it's used with as it wouldn't just
appear as an onboard processor.
Right. Currently it is offered as a PCIe card to compete with GPU
implementations. Given that Intel is also a chip vendor, there is no
reason why Xeon Phi can not be more integrated (e.g. on motherboard)
in the future. I don't see anything which prohibits it from serving
the function of a general purpose CPU with peripherals.
It would be very interesting to be able to support Xeon Phi cards on
an Illumos system and even more interesting if it was possible to boot
and run something like SmartOS on the co-processor card so it behaves
as an adjunct networked "host" device with 62 cores.
