I use the efi stub loader with refind bootloader. Refind doesn't have an option
to use outb as in grub. I have set OSX preferences to "battery saving", so that
the firmware sets up the 9400 initially, but the 9600 is still technically
enabled. It shows up in lspci, etc. Whenever I test the 9600, I change the
setting in OSX back to "performance". So yes, with both cards enabled, the 9400
works without corruption.

I've only tested the 9600 about 10 times, but I've always had corruption. I
will try your changes and see if it makes a difference.
