My ThinkPad R40 2681-5UU just came back from warranty repair with a new
motherboard and BIOS. dmidecode reports my BIOS as,

            Vendor: IBM
            Version: 1OET57WW (1.23 )

Anyhow, now I get new kernel messages upon startup. It tells me that:

Executing all Device _STA and_INI methods:..................................................... exfldio-0143 [22] ex_setup_region       : Field [PWKI] access width (4 bytes) too large for region [U7CS] (length 2)

 exfldio-0179: *** Warning: The ACPI AML in your computer contains errors, please nag the manufacturer to correct it.

.....

Does anyone else get this? Is this certainly some error in this new
BIOS? I don't fancy my chances of explaining it over the telephone to
Lenovo. The firewire support in Linux 2.6.8 now seems to get upset and
disable IRQ 11 where previously, before the motherboard change, it
didn't.
