Hi! I've found the problem on AMD-K62 and MMX. The culprit is the config.in (arch/i386) script, where K62 is removed (?) from the processors supporting 3DNOW (!!). This at least cures the problem for me (but robably not for i486 ?)
Here is a patch:

I'm not sure for AMD-K62 if the following should be enabled as well:
define_bool CONFIG_X86_GOOD_APIC y
