What _are_ you using? If you're going through the MTD device for the flash 
chip, calling its read() method, that still ought to work.

If you're trying to just read the compressed data in the flash chip directly
from the memory location you happen to know it's mapped at, you've just
demonstrated why XIP on a writable chips is such a pain :)
