Alienware acpi problem

[Steve Kargl]

ACPI gurus,

My colleague has installed FreeBSD 6.1-table onto his
Alienware MJ-12 laptop.  During the boot process, we
see

acpi0: [MPSAFE]
    ACPI-0438: *** Error: Looking up [\\_SB_.PCI0.PIB_.LNKH] in namespace, AE_NOT_FOUND
SearchNode 0xffffff000091c240 StartNode 0xffffff000091c240 ReturnNode 0

The system boots and appears to function (although cardbus seems broken).
I've roamed Alienware's web site and used google to search for an BIOS
update without success.

Are these messages something to worry about?  Anyone know how to fix
the problem.

I've put a verbose boot meesage at
