We will help you out however we can.

I can't help you with that issue in particular. I have been using a 1 GB
Microdrive as well as a 512 MB CF card.

Yes. Solid state storage is limited to something like 1000000 writes as
I remember. If you are doing writes to CF all the time because of swap,
in theory, you will rack up writes very quickly. I am not aware of
anyone actually running into this problem in practice though. On hpcmips
and hpcarm system I run without swap and with options enabled that
minimize disk writes.

Because NetBSD packages are binary compatible across multiple hardware
platforms, I just use a Cobalt RaQ 2+ to compile any programs I need.
Both NetBSD/hpcmips and NetBSD/cobalt generate mipsel (MIPS little
endian) packages. My RaQ 2+ has 256 MB of memory and a 40 GB disk so it
works just fine. I can compile packages for you if need be. I hope that
