RE: HP dv9000t battery discharge rate

I guess your DSDT does not support 'present rate'.
Look in /proc/acpi/BAT*/state file. The 'present rate' field is the PBST
at 0x01. I expect the 'unknown' (0xFFFFFFFF) value of 'present rate'. Is
it?

Subject: HP dv9000t battery discharge rate

Hi,
Was looking how to get battery discharge rate on this laptop.
This is part of DSDT:
            Name (PBST, Package (0x04)
            {
                0x00,
                0xFFFFFFFF,
                0xFFFFFFFF,
                0x2710
            })
...

            Method (_BST, 0, NotSerialized)
            {
                If (ECON)
                {
                    If (\_SB.PCI0.LPCB.EC0.MBTS)
                    {
                        UPBS ()
                    }
                    Else
                    {
                        IVBS ()
                    }
                }
                Else
                {
                    IVBS ()
                }

                Return (PBST)
            }
...
            Method (UPBS, 0, NotSerialized)
            {
                Store (\_SB.PCI0.LPCB.EC0.MBRM, Local5)
                If (LNot (And (Local5, 0x8000)))
                {
                    ShiftRight (Local5, 0x05, Local5)
                    ShiftLeft (Local5, 0x05, Local5)
                    If (LNotEqual (Local5, DerefOf (Index (PBST,
0x02))))
                    {
                        Store (Local5, Index (PBST, 0x02))
                    }
                }

                Store (\_SB.PCI0.LPCB.EC0.MBCV, Index (PBST, 0x03))
                Store (\_SB.PCI0.LPCB.EC0.MBST, Index (PBST, 0x00))
                Store (\_SB.PCI0.LPCB.EC0.BA1C, BCAP)
            }

and method IVBS just stores default values into PBST.
So, I'm not familiar with iasl and rest, but if I understand right, UPBS

method is used in case when battery connected and known to system.
In UPBS method I don't see any code that updates PBST at 0x01 
(discharge_rate). HP support says that sensor is present in system.
Any ideas where this sensor located and how can I get discharge rate 
visible in ACPI (kernel 2.6.18.2)?
