Um, because my NIS was incorrectly configured. Sorry for the blind
alley.
Adding nis and nisplus to the relevant entries in
/compat/linux/etc/nsswitch.conf means that linux id works dandy:
$ /compat/linux/usr/bin/id
uid=3D2139(faber) gid=3D134(div7) groups=3D0(wheel),5(operator),80(www),169=
(dartgrp),259(sys413),335(cs555fac),356(arpisi),387(crisis),402(ilense),546=
(xcp),584(webdiv7),605(rfcdev),7001(abac)
and the getpwnam_r error disappears.
The flashplugin still fails with the errors:
---

(npviewer.bin:52959): Gtk-WARNING **: cannot open display: :0.0

Sorry for the NIS noise.
