So that was the good case (all working as expected).

^^^^^^^^^^^^^^^
Hmm, I thought that this might be the case.
Can you please try to boot -rc7 with kernel parameter acpi_skip_timer_override
and send the same output (dmesg again also with apic=debug and lspci -nnxxxx)
Thanks,
Andreas
PS: My assumption is that the patch in -rc7 leads to usage of IO-APIC
pin2 for timer interrupt (potentially I have broken chipset
revision determination for some SB600.)
