If I cat /proc/iomem on a Sequoia board, it never stops printing.  Here 
are the first 10 lines:

Basically, the last line (regarding the nand flash) keeps repeating 
"forever".

Is anyone else seeing this behavior?  My kernel is 2.6.23 with Xenomai 
patched in.
    

Erm.. 2.6.23?  There is no Sequoia support in arch/ppc or arch/powerpc
for 2.6.23 in the official trees.  What is Xenomai?  You should
probably talk to them.
