Yes, I ran an unmodified 2.6.13 with a minimal but somewhat minimal userspace (sash, glibc) on an fpu-less 386. http://jengelh.hopto.org/GFX/mach/386sx.jpg http://jengelh.hopto.org/GFX/mach/proc386.jpg (yay, 3.09 bogomips and a totally incapable processor :p) Have not tried more recent kernels yet though.
