The proper fix for all of this mess is to fix the gcc compiler suite to actually generate i686 code when told to use i686. CMOV is an optional i686 extension which gcc uses without checking. In early PIV days it made sense but on modern processors CMOV is so pointless the bug should be fixed. At that point an i686 kernel would contain i686 instructions and actually run on all i686 processors ending all the i586 pain for most users and distributions.
Could you explain why CMOV is pointless now? Are there any benchmarks proving that?
