Dell Latitude E6400, F10-uptodate as of yesterday, 2.6.29-git14 plus Vegard Nossum's fix to acpi/battery.c to allow booting (this specific WARNING was also printed during -git13 boot, which would eventually hang prior to Vegard's patch).
dmesg excerpt:

System seems to work at the moment (apart from unrelated X/VT issues I plan to report in a detailed fashion by the end of this week).
