After recent changes, I cannot build  rtl28xxu on systems with linux
2.6.32 or 3.2.0.
rtl28xxu is one of the few drivers depending on  I2C_MUX.
Kconfig.kern lists I2C_MUX (correctly) as not in the kernel of the system.
I don't know if it is possible to load a new module for that.

Who can help me with this ?
