OK, then either the alias detection code is b0rken for that particular 
arrangement of chips, or the second pair is at some other physical address. 

Play with extending the virtual mapping even further, and if you can, stick
a logic analyser on the CE lines to the second pair of chips and work out
exactly which physical address does match them. You could also try setting
up the original mapping which you expect to include each pair just once, and
disabling the alias detection - then see if you really have got both pairs.

This would be more appropriately discussed on the MTD list than the JFFS 
list. If you can fix the problem reported at 
http://lookup.orbs.org/verify.php3?address=203.115.31.220 and then fill in 
the form at http://lookup.orbs.org/closed2.php3?address=203.115.31.220 then 
you should be able to post there. Until then, you may need to use an email 
account elsewhere if you wish to do so.
