Short one..
To read device id and manufacturer id from dual die S70GL02GT device, what would be the command sequence ?
We are using device in x16 mode.
a) Is it this ..
< 2 Byte writes at addresses.>
*(u16 *) 555 = 0xaaaa // unlock 1
*(u16 *) 2AA = 0x5555 // unlock 2
*(u16 *) 555 = 0x9090 // Command.

and set A26 high for second die and repeat a) ?

Second die is same as first die. The device ID for first die is the same as second die. Therefore A26 does not have any relevance reading Device ID. Refer to S70GL02GT datasheet Distinctive Characteristics and go bullet # 2.
Device Id in x16 mode is (ID-CFI):
Cycle 1 = 227Eh
Cycle 2 = 2248h
Cycle 3 = 2201h
