I've got a setup like that working now. I think the problem is that that you can't have the root partition past the 1024 logical cylinder due to BIOS issues - I surely would've liked to have been in on wrting that piece of code! Mind you, this machine hasn't swapped yet, which raises an OT question: what's the easiest way to get the machine to swap *hard*?
