Hi,
To add coretemp (thermal monitoring) support for the Intel Q9450 processor add the code below. i have tested this on several kernels including 2.6.26 and it works fine. the code addition is *||(c->x86_model == 0x17) in the if statement*
Thanks
Eric

*in:*
drivers/hwmon/coretemp.c
*in function:*
static int __init coretemp_init(void)

*change:*
if ((c->cpuid_level < 0) || (c->x86 != 0x6) ||
!((c->x86_model == 0xe) || (c->x86_model == 0xf) ||
(c->x86_model == 0x16))) {

/* supported CPU not found, but report the unknown
family 6 CPU */
if ((c->x86 == 0x6) && (c->x86_model > 0xf))
printk(KERN_WARNING DRVNAME ": Unknown CPU "
"model %x\n", c->x86_model);
continue;
}
*to*
if ((c->cpuid_level < 0) || (c->x86 != 0x6) ||
!((c->x86_model == 0xe) || (c->x86_model == 0xf) ||
(c->x86_model == 0x16)*||(c->x86_model == 0x17)*)) {

/* supported CPU not found, but report the unknown
family 6 CPU */
if ((c->x86 == 0x6) && (c->x86_model > 0xf))
printk(KERN_WARNING DRVNAME ": Unknown CPU "
"model %x\n", c->x86_model);
continue;
}
