It appears that the 2.6.13 kernel did not bring up the machine's io-APICs,

perhaps that's not relevant.

It looks like he's _not_ receiving eth0 interrupts if I'm not mistaken?

Correct no interrupts received under 2.6.16
and this:

..TIMER: vector=0x31 apic1=-1 pin1=-1 apic2=-1 pin2=-1
...trying to set up timer (IRQ0) through the 8259A ... failed.
...trying to set up timer as Virtual Wire IRQ... works.

looks suspiciously like a broken apic/code/workaround/whatever

I'd go with Andrew's suggestion and disable apic in your bootparameters (noapic and/or nolapic) and possibly in your config if it corrects i
Adding noapic works. I have ethernet back.

Do you need me to log a bug report somewhere about this?
