In fact that didn't work at all well. At the time I was running fdisk it did 
appear to be doing as expected, but this morning when I came to start the 
system, grub's character set had been corrupted (or a pointer to it). I got 
just "GRUB " followed by half a line of graphics characters. So clearly, 
rather more than just the partition-type field is being overwritten.

I had to boot a CD, delete then re-create /dev/hda1, chroot to the installed 
system and run grub again to reinstall itself, just as I had been doing.

Before raising a bug report, I'm going to recompile the entire system 
with -O2 in place of the -Os that I have at the moment. I can't see how 
that could be causing this problem, but I want to be sure.
