Yes.... but I just checked now the init sequence in the Linux kernel 
driver and it's different from the default :/

The 10b value is stored in two registers: 0x4002 BLC[9:8] as LSBs and 
0x4003 for BLC[7:0]. The default value is indeed 0x00 and 0x10, BUT the 
driver sets 0x4003 to 0x40 so I think this needs to be 0x40? Can you see 
if this makes things better?

Cheers,
Quentin
