Greetings Jean-

When attempting a dump of the device at 0x4c, I do *not* get any 'XX' output. What is interesting is that when running 'i2cdetect -y 0', the device at 0x19 shows up only sporadically. It is not present in every run of i2cdetect. The other device at 0x4c shows up every time, and does not contain 'XX' output. Is it safe to assume there is a problem with the Winbond controller? Or, it's usage on this board (hardware problem?) ?

I attempted to load the scx200_i2c module but I'm greeted with:

FATAL: Error inserting scx200_i2c (/lib/modules/2.6.26-2-486/kernel/drivers/i2c/busses/scx200_i2c.ko): No such device

I've tried with and without having the scx200_acb module loaded.

Thoughts?
