As I said before I believe the 25MHz crystal is for the network I/F chip. Is x3 populated, this is the footprint for the processor crystal? The firmware has never supported 25Mhz only ever 8MHz. The firmware works works perfectly on my ZI but that has the Y chip. Do you have a battery installed or have you left SB156 in place? One of these is essential.
The latest firmware uses the chip version to correctly configure the chip, some of this is done by me but the HAL also has version differences and I updated the HAL in the latest releases. It could be you have some sort of bastard chip as AFAIK the ZI ws never supposed to have shipped with a V chip
