Is the swimming typical for bilinear minification (probably)? or just plain
broken (make sure you have all IRIX 5.3 RE/GL patches)?

Older Flight Loaders for Performer 1.x forced MIPMAP_TRILINEAR minification on
all textures, when running on Reality Engine. The V11, V13 and V14 (and also
.dwb) loaders, shipped with Performer 1.2, have this common (an SGI decision)
texture filter behavior.
As a history note, I first enabled full use of MultiGen texture .attr files in
June 1994 with loader release R14.1a for 1.2 (one of my first feature
enhancements to the loader :-).
Regards.
