yes

Just FYI, 2.6.23, 2.6.24 and 2.6.25-rc6 work fine on my i486DX4.
However, it's clear from your .config fragment above that you've enabled features that cannot possibly exist on a 486 (APICs and MCE for starters) and there may be bugs related to that. I suggest trimming your .config and making it 486-specific.
