I think I figured it out.
The problem was actually with xorg. For whatever reason, it seems to ignore
the DefaultDepth directive in the xorg.cfg and so my X was actually being
started in 16-bit mode, despite DefaultDepth being set to 24. (I was
wondering about some of the banding issues I was seeing!) How it was
managing to do 6/6/6 in 16-bit mode is beyond me, since 6*3 = 18 > 16.
But anyway, starting X with '-depth 24' seems to work around the problem and
forces X into 24 bit 8/8/8 mode, which works fine with Argyll.
Thanks :)
