Actually, I should refine that - if you really need max performance, you
could lock in the dedicated chipset in the BIOS and use the proprietary
driver, and that should work, with all the usual trade-offs associated
with proprietary drivers. It's the 'hybrid' function specifically that
you can't really use under Linux, because the proprietary drivers don't
support it, and even if you can get the rudimentary support in the open
drivers to work, the open driver for the 'faster' chipset is likely to
be slower than the one for the Intel chip anyway.
