Well, but inside of 100BASE-BX there is space to mark it as BIDI. The 
only reasonable choice is LX.
If BIDI modules will be configured (in EEPROM) as LX modules - they will 
work fine.

I guess they are made for Cisco without any standard information about 
beeing LX in EEPROM,
so the switch doesn't know how to treat the module.
Same happens if you put STM-4 module in a switch, it is marked then as 
STM-4 and no ethernet.
The only multi configuration is possible for multi-rate modules (with 
i.e. max speed 2.6G).
These are set to be 100Base-LX, 1000BaseLX, STM-1, STM-4, STM-16, 
Etherchannel (whatever except 4G) etc...
