Summarizing the present situation:

- There's a BIOS-induced conflict between PNP and PCI on these laptops.
- Arne's patch fixes this specifically for the laptop's hardware -- the patch should be safe to apply since it will not affect any machines other than these laptops.
- The BIOS inconsistency can be seen in the ACPI table, therefore there's scope for the kernel being able to fix this type of problem all by itself.
- Upstream, Jesse Barnes is trying to come up with a general solution for this type of conflicts. Some progress has been made, but it's not quite there yet.
- In the meantime, he's suggested that we apply Arne's patch to the Ubuntu kernel.
- This patch makes the one associated with LP bug #90271 ("Compile RealTek 8139 using PIO method") obsolete -- it should be removed.
