I am going to make myself very unpopular to suggest this: use the vendor driver.
Here is a passage from around line 236 of zd_mac.c:
/* At this point, the vendor driver downloads the whole firmware
* image, hacks around with version IDs, and uploads it again,
* completely overwriting the boot code. We do not do this here as
* it is not required on any tested devices, and it is suspected to
* cause problems. */
So the zd1211rw code doesn't cope with your situation, and it is a known
problem. I don't think you will get better answers at linux-wireless mailing
list. The manufacturer is being a bit funny in mislabelling the devices.
(And, really, you should have approached your distro's bug tracking system
first).
