Does this apply generally to all P4's, or just a subset? If all, it may be we want to add a P4-workaround to GENERIC so that P4's work better ouf of the box. If it's a select few, I wonder if there's some way to test for the problem early in the boot... One of the recurring themes here has (a) been P4 processors, and (b) been a fear that because of timing changes introduced by the DISABLE_FOO flags, the real bug is still there, but less visible in the tests people are running.
