i had a look at diff -up dmesg-2.6.25.8.txt dmesg-2.6.26.2.txt, and
these changes stood out:
ACPI: bus type pci registered
-PCI: BIOS Bug: MCFG area at f8000000 is not E820-reserved
+PCI: MCFG configuration 0: base f8000000 segment 0 buses 0 - 63

- PREFETCH window: 0x0000000060000000-0x0000000063ffffff
+ PREFETCH window: disabled.
so a quirk that triggered previously does not seem to trigger anymore.
find below some of the other deltas. I edited out the dmesg deltas that
i considered non-interesting - this should make it shorter/easier for
others to review the changes.
