Mike and Stefan,

>Could you please check, if the 460SX has the same registers and bits as
>460EX/GT and extend its header as well?

[marri] 460Ex/Gt and 460Sx has different clocking subsystems. This code
will
 Have to split to support to read the speed settings from CPU registers.

 If you can include the change to split this function we will submit our
patch
Based on yours. Please suggest.

Thanks,
Marri
