That's good to know. Any hints on the generation of a suitable initrd?
I'm guessing that's going to be the difficult bit.

I feared that might be the case. I do have a spare drive here, so I
suppose that's not really going to be an issue, provided that when
I'm up and running from NFS, I can install freshly built versions
of mythfrontend without connecting up the drive. If both server and
client were running 64bit opensuse, I could just chroot into the
NFS-exported directory presumably, but with the server being 64bit
and the client 32bit, I imagine there could be problems. (Am I
right that the Zotac ION can't run 64bit code?)

Ah no. I was hoping for just an instant power-off death. Minimyth
was fine with doing that because the writable parts of the system
were in ramfs.
