There's a bug in one of the ASICs used on some 67xx linecards that eats a block 
64 vlans.  Same problem exists on Nexus.  Unfortunately, NX-OS doesn't yet have 
the ability to relocate that "hole" like IOS does.  Biggest issue for us is 
that on nx-os, you can't even list those vlans in your MST config (nx-os just 
removes the vlan mappins and rewrites our config).  The result for us is that 
the vlan mapping config on our nx-os boxes doesn't match our IOS boxes so they 
think they are in their own region.  Sucks badly but should be fixed when nx-os 
picks up CSCtc54335.
