Full featured I2C driver?

[perf]

Hi!

I have an advanced i2c chip which require write/read (mangling) sequences.
However, I cannot see that the version I am running on my Maxi supports it.

My OS is:
Linux alarm 2.6.35-8-ARCH+ #1 PREEMPT Fri Sep 21 17:02:25 UTC 2012 armv5tejl GNU/Linux

Is my finding correct?
Are there any full-featured i2c drivers available for the Olinuxino Maxi?
