  just for fun, i addressed the only thing that was stopping me, and
that was that runqemu was looking for a slightly different sysroots
directory name than the toolchain provided, so:

/opt/poky/1.1/sysroots$ sudo ln -s x86_64-pokysdk-linux/ x86_64-linux

and then ran:

$ TMPDIR=/opt/poky/1.1 runqemu qemuarm zImage-2.6.37-qemuarm-1.0.bin
core-image-minimal-qemuarm.ext3

and it worked.  yes, i'm sure i'm abusing all sorts of things but, in
the end, once i dug through it, it seemed fairly easy to get it to
work.
