Ok, thanks, you've been a hero.

This cuts the changes down quite significantly. The shortlog between 
rc1-bk8 and rc1-bk9 is (if I did everything right - since that's from the 
BK days and I obviously don't have BK installed anywhere, I had to convert 
things into git to make sense of it) appended.

I _suspect_ it's the IDE changes: perhaps the fact that we enable IDE 
"stroke" by default now, which unclips the IDE disk. Maybe the BIOS is 
unhappy with that.

In your "dmesg" for a modern kernel, do you get a message like

	...: Host Protected Area detected.
		current capacity is .. sectors (.. MB)
		native  capacity is .. sectors (.. MB)

if so, that's probably it, and you could try this patch.

If that doesn't help, I can help you bisect the problem down to a smaller 
patch, if you're willing to try some patches I'd send by email?
