By the looks of it, chances are that various APIC fixes and robustization patches might have fixed your problem:

691874f: x86: I/O APIC: timer through 8259A second-chance
03be750: x86: I/O APIC: keep the timer IRQ masked during set-up
24742ec: x86: I/O APIC: unmask the second-chance timer interrupt
d11d579: x86: I/O APIC: AEOI timer acknowledgement clean-ups

These first showed up in v2.6.27. Which would match your reported symptoms of v2.6.26 failig and 2.6.28 working.

Yes, you're right. Looking at the detailed kernel messages, the "8259A second-chance" seems to do the trick. So it's already tackled. :-)
