It is good to hear this. Please check number of RWW partitons
(numvirtchips variable) and 9th bit of extp->FeatureSupport. 
Everything is Ok if numvirtchips == 1 or extp->FeatureSupport bit 9 is 0.

As I remember some versions of MTD prior to 2.6.17 had
problems with CFI offset calculation. It led chip to be identified as
multiple partitioned device when it should have 1 partiton. 

Thanks,
Alexey
