Ok, let's fix it then. Unfortunately, I don't think I will have time for 
this _soon_, but I definitely will try to convret all i.MX31 platforms to 
CFG_HZ == 1000 ASAP. Jean-Christophe, what would you prefer, first accept 
patches as they are (i.e., with CFG_HZ ~= 1000) and then fix all i.MX31 
platforms or first fix the existing boards and then commit an updated 
patch with CFG_HZ == 1000?

Thanks
