This is Maciej's patch - latest posting of it that I have seen,

His fix up of the 8259 ack issue (when used without routing 8254 pit into
io-apic INTIN0) successfully establishes a virtual wire mode input of the timer
which the nforce2 seems happy with albeit without being able to use

It is that timer ack issue tied up with the integrated apic.

This refers to when it was in the 2.6.3-rc1-mm1
