That would have been a better starting place I guess, but what I did was
find a .config on the web, and used that with "make oldconfig", then
modified to taste.
Turns out the problem above was caused by the SuSE kernel taking the
partitions fdisk laid out over what IBM set up (with the pre-desktop
area), and the stock kernel did the reverse. /usr went to the end of the
disk (through the pre-desktop area) so SuSE kernel read it fine, but stock
kernel couldn't read last part of it. Redefining /usr fixed it.
