I'm going to get DFS into the 7448 (it looks like I'm going to take a
different
tactic then I see in 2.6.20.16 -- it hinges on powermac, and I don't
know if it
even compiles).
In include/asm-powerpc, its missing definitions for HID1/{PC4,PC5}.

PC4 seems "generic", PC5 is a "MPC7448 specific bit"
I'm not sure what HID1_PS means ( 750FX PLL selection ), its the same
bit as=20
HID1_PC0.

Do you want this patch in the kernel? If so we'll need a signed-off-by.
