i am just trying to install lm_sensors but when i start the service module it87 fails to load

Code:
desktop ~ # /etc/init.d/lm_sensors start
 * Caching service dependencies ...                                       [ ok ]
 * Loading lm_sensors modules...
 *   Loading it87 ...                                                     [ !! ]
 * Initializing sensors ...                                               [ ok ]


so how do i fix this?

Check whether the module exists at all.
Code:
# find /lib/modules -name it87.ko
Also try to run modprobe it87 manually and watch dmesg output for errors.

it seems its being used by something else..

Code:
desktop ~ # find /lib/modules -name it87.ko
/lib/modules/3.5.7-gentoo/kernel/drivers/hwmon/it87.ko


Code:
desktop ~ # modprobe it87
FATAL: Error inserting it87 (/lib/modules/3.5.7-gentoo/kernel/drivers/hwmon/it87.ko): Device or resource busy


Code:
desktop ~ # dmesg | grep it87 
it87: Found IT8716F chip at 0x290, revision 1
it87: Found IT8716F chip at 0x290, revision 1


so how do i make it available for lm_sensors?

This is a problem that has hit me, and I understands is common on ASUS motherboards. The IT87 module is not "ACPI-compliant", and ACPI has grabbed that resource, preventing IT87 from getting it. There are 2 ways around this. There is a kernel option to relax that restriction, which in some cases can be dangerous, but isn't really in this one. (acpi_enforce_resources=lax) The other way is with an alternative driver that is ACPI-compliant driver, I believe called "asus_atk0110".

This issue is discussed here as: http://forums-web2.gentoo.org/viewtopic-t-832524-start-0.html
