Do you have other Sandpoint X3 chasis around?  At one point I managed to
convince myself that I had a chasis with busted IDE support by taking
the same PMC card, same binary kernel and two X3 chasis.  Same harddrive
would work on one, not the other.  This, along with trying a more recent
kernel might be a good idea.  Also, I see you modified the kernel to use
all 128mb of memory.  Try going back to the hard-coded 32mb of memory.
