Yes, but for a kernel developer anything out of Linux (whether higher in the food chain or lower) is 'userspace'. Even BIOS. Whne people say that Kernel<->Userspace interface is set in stone, they really mean Kernel<->Anything-that-is-not-the-kernel.

That's not the case. We've broken the Linux <-> BIOS interface several times in ACPI, though admittedly every time it's been to make ourselves look more like Windows.
