How did you physically verify this?
Oszi show 166MHz, also the kernel message about freq are in both kernels the
same.

Can you upgrade to a newer u-boot? Either from the PSP release
OR u-boot tree hosted at git.denx.de (atleast 2009.03)?
Also, it will be good to see the sample program you are using.

There is no newer u-boot from TI available. There is a SDK 02.01.03.11
but it contains the

I don't know - can it be configured or misconfigured somehow?
I just checked the output of 2.6.22 kernel and get these lines (which I don't
