It wouldn't surprise me if that were the case. I've had some pretty weird firmware related issues with other Lenovo systems before (like the brightness hot-keys causing the reported trip points for ACPI thermal zones to temporarily change).look further into the options I have set in my kernel build, I may have changed something else without remembering between booting with and without the CSM enabled.It could also be that the non-CSM BIOS somehow remaps the CMOS registers.I don't believe there is anything which prevents the CSM from faking a CMOS clock using SMM from whatever is actually in the hardware.

I've rebuilt the kernel I'm using with everything I can think of possibly depending on the CSM compiled out or as modules, so I'll hopefully have some more info soon.
