Here you go :

BootX :

*fde69000 = 10000000
*fde69004 = 00000000
*fde69008 = 04000000
*fde6900c = 00000000
*fde69010 = 04101102
*fde69014 = 00000000
*fde69018 = 00000345
*fde6901c = 00000000

Quik:

*fdeff000 = 10000000
*fdeff004 = 00000000
*fdeff008 = 04000000
*fdeff00c = 00000000
*fdeff010 = 04101102
*fdeff014 = 00000000
*fdeff018 = 00000345
*fdeff01c = 00000000

Except for the ioremap address being different, not much to see
here...

BenH> It could be something else tho ... like some problem with
BenH> quik...

I fear that... But even in such a case ,understanding what confuses
the kernel would help a lot...

Thanks for your help,
