I'd start with examining the coreboot console log. Are there resource conflicts? Are all APs initialized? Was the microcode updated for all of them? etc... If you don't have it already, you can grab the log from your running non-smp OS with `cbmem -c` (see util/cbmem/ in the coreboot tree). Feel free to attach it, if you want somebody else to look through it.
Unfortunately nothing obvious pops in the log, at least for my sight. Please don`t mind invalid PNP mappings from both SIOs and corresponding Linux warnings, these are leftovers from using t60 skeleton. I am attaching combined log from coreboot, SeaBIOS and Linux with UP kernel for the reference.
