For the record, it finally happened. I posted a patch doing this on
the linux-i2c list on May 4th, which can be temporarily seen at:
ftp://ftp.kernel.org/pub/linux/kernel/people/jdelvare/linux-2.6/jdelvare-i2c/i2c-sysfs-interface-to-instantiate-devices.patch

It will be merged in 2.6.31. Potential users are invited to give it a
try and comment by then. Hopefully we can then deprecate the ugly
I2C_CLIENT_INSMOD* macros, and get rid of them 2 kernels later.

Thanks,
