I'm just about moving again here, but with a decided limp: the system 
that blew was 2.8GHz and all my guest OSes are now plugged into a 1GHz 
box. I still find being able to use a significant number of different 
guests in sleds/caddies useful... Unfortunately I've still not got any 
real MIPS hardware running here, so I'm still stuck on Qemu.

The good news is that I can still run/build trunk for mipsel on Debian 
"Squeeze" on Qemu without unanticipated issues (i.e. nobody reading this 
should assume that Lazarus will work yet).

The not-so-good news is that I built from trunk earlier but after having 
bus errors in Qemu's implementation of big-endian MIPS I'm now looking 
at the file above. Unfortunately I still get bus errors and I think the 
binaries have been stripped.

If I revert to a binary that I cross-built from trunk earlier, I get this:
