BI 0903 BLAK-8GB
BI 0905 BLCK-8GB
BH 0906 BMTK-4GB
BI 0909 BMYK-8GB
BI 0912 BMTK-8GB
BI 1001 BMTK-8GB
BI 1003 BMTK-8GB
BH 1004 CABK-4GB

Units that doesnt accept firmwares other then 02.03.31-OF and 02.03.33-OF:
BI 1004 CAHK-8GB (3 units with this number already)
The numbers look like the date code YYMM.
For the letters I dont really have an idea.

First two letters of the code, e.g. BH and BI would seem like it indicates the capacity. BH for 4GB and BI for 8GB. As you said the middle four numbers look like a date code. The last four letters are what I'm stuck on. A part of me wants to say one or two letters indicate colour, but I can't be 100% sure.

So, regarding the Fuzu wont accept RB-Flash:
So I have calles Sandisk about the "issue" and the nice women said that they are aware of it, the ready it already in the forums and im the second person that asks fot that. At the same sentence she says also, that she is sorry, but that this (issue) is made that people "dont make this" (... use alternative firmware?!) anymore.
She still tries to help and is trying to get a official announcement for that.
I think I wait for 2-3 days and then im returning my unit and trying to get another one.

I am not sure why they care at all, perhaps they were returned several "defective" players with rockbox installed?
EDIT:
You can try this to see how the protection they added is effective:
Be sure you want to risk bricking your fuze by running modified code
* Open a working OF file in an hex editor and swap 2 characters
* The characters must be distant of a multiple of 4 bytes, because the checksum is calculated as a sum of 32bits numbers
* For example swap a character at position N and position N+4, the firmware will be different but the checksum will be the same
* At position 0x38090 (outside the firmware block, in the "drmndt_pers" library block) there is the string "http://go.microsoft.com/fwlink/?LinkId=28745", make that be ":ttph//go.microsoft.com/fwlink/?LinkId=28745" (h and : swapped)
* Try to patch that OF, see if it works (I don't know how to display this string, it must be related to WMA drm)
* At position 0x216d9 (inside firmware block), there is the string "Hiphop", make that "oiphHp", see if the OF can be patched
