[ACPI] No handler for Region [ERAM] on Gateway M350?

[Dan <da...@in...>]

Hello,

  I've recently been trying to get ACPI support up and running on my
Gateway M350 laptop...using kernel 2.6.1.  Everything seems to appear
just fine in /proc/acpi, except for the battery information;
/proc/acpi/battery exists, but there is nothing in the directory =( 
There is a series of error messages (AE_NOT_EXIST) in the dmesg output
relating to it, preceeded by a "No Handler for Region [ERAM]" error that
I suspect is the source of the other problems.  The kernel config with
regards to ACPI is as follows:

# Power management options (ACPI, APM)
# ACPI (Advanced Configuration and Power Interface) Support
CONFIG_ACPI=y
CONFIG_ACPI_BOOT=y
CONFIG_ACPI_INTERPRETER=y
CONFIG_ACPI_SLEEP=y
CONFIG_ACPI_SLEEP_PROC_FS=y
CONFIG_ACPI_AC=y
CONFIG_ACPI_BATTERY=y
CONFIG_ACPI_BUTTON=y
CONFIG_ACPI_FAN=y
CONFIG_ACPI_PROCESSOR=y
CONFIG_ACPI_THERMAL=y
# CONFIG_ACPI_ASUS is not set
# CONFIG_ACPI_TOSHIBA is not set
# CONFIG_ACPI_DEBUG is not set
CONFIG_ACPI_BUS=y
CONFIG_ACPI_EC=y
CONFIG_ACPI_POWER=y
CONFIG_ACPI_PCI=y
CONFIG_ACPI_SYSTEM=y
# CONFIG_ACPI_RELAXED_AML is not set
# CONFIG_SERIAL_8250_ACPI is not set
~~~~~~~~~~~~End .config~~~~~~~~~~~

The relevant section of dmesg is:

~~~~~~~~~~End dmesg~~~~~~~~~~~~~~

As you can see in the above section, the first error (and what I suspect
is causing the subsequent AE_NOT_EXIST errors) is the "No Handler for
Region [ERAM]" message that I can't seem to diagnose.  I've attached a
dump of my DSDT data, after running it through acpidmp, in case it's
relevant (bzipped so that it's not 200+K =P).  Any ideas at all would be
MOST appreciated =)  Thanks so much!
