How do I do that?

Both -- the hanging ed1 and the working wi0 are 16bit 5volt cards, according 
to their labeling. Prior to the ed1-hang, there is a message about 32 cfe 
allocation failure.

Less layers, and (slightly) more diskspace -- just feels neater, I guess. But 
the BIOS would not boot, so out with it in this case.

According to systat and top, the CPU is never idle -- as would've been the 
case, if the I/O were the limiting factor. The Sys-component of `systat -vm'
was steadily above 50%.

Now that I have a witness-less kernel, the builds are, indeed, I/O bound.
