Active Management Technology is independent of the operating system as it is implemented in the hardware and firmware of the machine.
However, some of the usage models require local host device drivers (for example you if you want to store software inventory in AMT's 3rd Party Data Store, you would need operating system drivers). http://www.openamt.orgis a site that provides help with opensource AMT drivers and tools. You may be able to get help here for building drivers for Solaris.
