Folks:
	I've just made room on my T30 to install NetBSD and while I have
	a lot of stuff working and configured now, there's a serious issue
	with me not being able to get battery status via ACPI (APM seemed
	to hand the machine and ACPI has the added bonus of helping out
	with autoconfiguration, so I figured I'd go that route).

	Here's a summary of what happens:

Machine/kernel info (and a bunch of ACPI errors), sources are from after
Thor's fixes to the bufcache code (sources probably from Fri night):

	acpi0: SCI interrupting at int 9

envstat -l reports lots of interesting fields about the batteries:
	acpibat0 present
	acpibat0 design cap
	acpibat0 last full cap
	acpibat0 technology
	acpibat0 design voltage
	acpibat0 warn cap
	acpibat0 low cap
	acpibat0 voltage
	acpibat0 charge rate
	acpibat0 discharge rate
	acpibat0 charge
	acpibat0 charging
	acpibat0 discharging
	acpibat1 present
	acpibat1 design cap
	acpibat1 last full cap
	acpibat1 technology
	acpibat1 design voltage
	acpibat1 warn cap
	acpibat1 low cap
	acpibat1 voltage
	acpibat1 charge rate
	acpibat1 discharge rate
	acpibat1 charge
	acpibat1 charging
	acpibat1 discharging
	acpiacad0 connected
	acpiacad0 disconnected
	acpitz0 temperature

However, many of the really interesting fields are not retrieved correctly:

     acpibat0 design cap    acpibat0 charge rate acpibat0 discharge rate         acpibat0 charge       acpibat0 charging    acpibat0 discharging
                      Wh                       W                       W                      Wh                    bool                    bool
                   47.52                       *                       *                       *                       *                       *

While performing this query, the kernel outputs:
	ACPI-1290: *** Error: Method execution failed [\_SB_.PCI0.LPC_.EC__.GBST] (Node 0xc0a1e140), AE_AML_INTERNAL
	ACPI-1290: *** Error: Method execution failed [\_SB_.PCI0.LPC_.EC__.BAT0._BST] (Node 0xc0a1e000), AE_AML_INTERNAL
	acpibat0: failed to evaluate _BST: AE_AML_INTERNAL

note that I get a some other errors from the battery as well (I think this
may be due to the acpitz 30s poll?):
	
	acpibat0: failed to evaluate _BST: AE_TYPE
	acpibat0: failed to evaluate _BST: AE_TYPE
	acpibat0: failed to evaluate _BST: AE_TYPE

But some parameters are retrieved fine, including the manf and chemistry
info:
	acpibat0 at acpi0 (PNP0C0A-0): ACPI Battery (Control Method)
	acpibat1 at acpi0 (PNP0C0A-1): ACPI Battery (Control Method)
	acpibat0: battery info: SANYO, LION, IBM-02K7072,  2965

And envstat -r does report correct-looking values for other battery data:
	
	       acpibat0 present
	    acpibat0 design cap:     47.520 Wh
	 acpibat0 last full cap:     37.880 Wh
	    acpibat0 technology:          1
	acpibat0 design voltage:     10.800 V
	      acpibat0 warn cap:      1.894 Wh ( 5.00%)
	       acpibat0 low cap:      0.200 Wh ( 0.53%)
	 acpiacad0 disconnected
	    acpitz0 temperature:     49.050 degC

Any clues/hints?

Thanks!
