Jeff,

Please attach the output from acpidump for your dell to this bug report:
https://bugzilla.kernel.org/show_bug.cgi?id=15886

I think we know how to cleanly solve the issue to make Philip's Gigabye
happy, and I'd like to know if your Dell is the same situation
or a different one.

Unfortunately, Matthew's HP fails for a different reason than Philip's 
Gigabyete.  (The BIOS asks for it - so we'll have to poke at the chipset
to find out the reason it is setting BM_STS)

thanks,
Len Brown, Intel Open Source Technology Center
