Summary

Make it under SI_SUB_CPU sysinit, instead of much later SI_SUB_DRIVERS. The SI_SUB_DRIVERS survived from times when FPU used real ISA attachment, now it is only pnp stub claiming id.

Can this be SI_ORDER_ANY? I can't recall if there is a specific order to the SI_SUB_CPU inits.

kib marked an inline comment as done.

Use SI_ORDER_ANY on amd64, same as on i386.
