no dice. here's the configuration in chip terms, followed by my config settings, followed by the driver ouput.
suggestions?

two banks. each bank is 32bit data, 32MB in size, made up of 2 chips in parallel. each chip is 16MB x 16bit data, organized as (128) 128KB sectors.
wiring: 0-32MB = 2x Intel 28F128J3A-150
address space 0x0000 0000 - 0200 0000
Shared: Flash A0 = Gnd Flash A1:A23 = PXA A2:24 Flash CE = PXA FlashBank 0 CE
Separate: Chip A: D00:15 = PXA D00:15 Chip B: D16:31 = PXA D16:31
address space 0x0200 0000 - 0400 0000
Shared: Flash A0 = Gnd Flash A1:A23 = PXA A2:24 Flash CE = PXA FlashBank 1 CE
Separate: Chip A: D00:15 = PXA D00:15 Chip B: D16:31 = PXA D16:31
