Thanks much for the quick response and the offer of assistance. Would it 
be possible to have the information programmatically available such that 
kobs-ng (or some other application) could read/determine it itself 
either via a sysfs node like the previous driver or some other method to 
export the information to user space? A manually triggered debug log 
would remove the need to boot an older kernel to determine the 
information, but would still require a user to transcribe the 
information from the log to kobs-ng. If the sysfs node or other export 
mechanism was only available if a particular command line option was 
supplied to the kernel to avoid contaminating the environments of people 
not interested in such a feature that would be fine.

I assume someday Freescale will update their BSP kernel to a newer 
version and run into this issue themselves :), so having this 
information available programmatically in a current kernel will perhaps 
make their lives easier someday ;).

Thanks again…
