It's not a bad interaction between i915 and radeon per se.  The switcheroo code
needs more work to switch properly on some systems it seems.  There are a set
acpi methods required to activate/deactivate the respective gpus.  The drivers
need to load and initialize active hw.  If the hw is not active when the driver
loads, then the hw is not set up properly and it won't work.  Probably some
ordering issues in how the switcheroo acpi methods are called.
