Well, after quite a bit more work, I'm still none the wiser. I've built a 
new installation from scratch without the ~amd64 key word, and I've tried 
many combinations of kernel parameters. Once or twice I thought I'd found 
it: for instance, it seemed that removing I2C completely caused the faulty 
behaviour to appear, but then putting it back in didn't correct it.

The new system is as independent of the original as possible. The old one 
was on /dev/hd[a,b] and the new is on /dev/sda, which is a SATA disk. I've 
changed the BIOS to boot from SATA first, though I couldn't hide the old 
disks completely - the IDE optical disks /dev/hd[c,d] were then hidden as 
well.

I started with a genkernel kernel, remembering to enable SATA in it 
first  ;-) , then switched to compiling manually, progressively stripping 
out all the extraneous modules and inbuilt features until I had a 
reasonably well tuned kernel. it works just fine.

I also reverted the BIOS to an optimised set of defaults and changed one 
thing at a time to reach (what I think is) the optimum for me. The system 
is working as it should. Soon I'll erase the old partitions - when I'm sure 
I don't need anything else off them.

So I can't put a case together to raise a bug report, and I'll have to 
accept just-one-of-those-things.
