No, /proc/bus is no longer used for i2c busses on 2.6 kernels.

The SMBus quirk was ruled unsafe when suspend support is enabled in the
kernel, so late 2.6.16 and later kernels disable the quirk when suspend

your choices are:
1* Ask Asus for a BIOS update where the SMBus is no longer hidden.
2* Recompile a kernel without suspend support.
