First time i did have to apply drivers on Solaris at installation time, and was a good experience. This blade servers have SAS discs, and there is no drivers on Solaris by default. Here you can find the needed drivers (storage, network, etc), and good installation instructions. I will make some tests with that system (the remote console that should need just JRE, is not working, just the IE/Active X thing..), and will post some ideas about it.
