I built a RAMDISK kernel with the sun3trap patch and DDB enabled. (Well,
first I build a 1.6 compat toolchain, *then* 24 hours of compiling later I
built a 1.6 kernel ;)

Unfortunately it can't seem to mount the ramdisk root filesystem. Only
change from the stock RAMDISK config was to enable DDB.

Do I need, perhaps, to build a ramdisk filesystem image as a second step?
Any hints? Boot messages follow...
