Without the parameters it has exactly zero effect on the operation of the kernel, the algorithms and the behaviour. So something odd is afoot if its causing gentoo breakages. Do you see this using a reasonably trustworthy compiler suite as we've not seen it on Fedora ? If you do does the box log any stuck IRQ's during boot without the patch
