The kernel built with MCRUSOE is unbootable on Transmeta Crusoe. It shows the following error message: This kernel requires an i686 CPU, but only detected an i586 CPU. Unable to boot - please use a kernel appropriate for your CPU. Remove MCRUSOE from the condition introduced in commit in Fixes, effectively changing X86_MINIMUM_CPU_FAMILY back to 5 on that machine, which matches the CPU family given by CPUID.
