CONFIG_SMP=y - no difference - like I say it's PF# on lock prefix
instructions, not SMP=y that's the problem here
CONFIG_M686=y (doesnt' boot)
CONFIG_M586TSC=y does boot
So yes M686 is not bootable on this part. My point to you about having a
custom kernel though still stands, you shouldn't have to compile a quark
specific kernel - just a 586TSC kernel with Quark support.
For example CentOS is bootable on Quark.
