I had taken care of the issue long time back but, for some reason, 2.6.15.2 kernel still has following conditional statement in the Kconfig.megaraid. --- if MEGARAID_NEWGEN=n config MEGARAID_LEGACY ... ... endif --- This condition prevents 'LSI Logic Legacy MegaRAID driver' to be available as an option. So, it has to be as follows, --- config MEGARAID_LEGACY ... ... --- If you use the kernel available on git and do 'make menuconfig', you will see this option available and you will be able to load megaraid driver v2.00.3 for the HP controllers.
