I read about the possible relation to a floppy, so I compiled without 
fdc support (my laptop doesn't have one anyway), though I still had the 
problem. I found one problem, there's another, though. I have one 
configuration file that will boot and one that won't. I haven't found 
what causes it yet, although the file that will boot is far less than 
optimal.

Thanks, I figured that out already, although I used rdiff. I do have a 
local copy of the repository.
