Okay, this all makes more sense now.  If I switch SW4:8 FCFG to '1',
then the config is read from the flash (so it must not depend on I2C).
The BMS was a red herring.  This means that the final RCW settings
should be:

=> md.b e2400000 20
e2400000: 2f 0c 40 08 86 af 07 33 ff ff 47 12 ff ff ff 02
/. at ....3..G.....
e2400010: 22 07 05 19 24 ff ff ff ff ff ff ff ff ff ff ff
"...$...........


(note at e2400000 now because I am running on new u-boot source).  

I was off-by-one... e240000 is BSCSR10 not BCSR11, so other people
should have the same value for this register.

Thanks again to everyone!
