Description

The i915 driver contains debugging code which returns a 'float', on x86 this will (iirc) be in the FPU, and on amd64 it will be in %xmm0, neither of which is safe to touch from arbitrary kernel code.

The code to do this should be ripped out and the floats printed in integer form (with a note that they're raw floats).
