Subject: [Fwd: how to add support in coretemp.c for Q9450 processor]


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
