I have built a number of previous kernels, but am having problems with
2.6.20.

I initially tried just changing only the Processor type (so what I had done would be easy to describe). Someone on this list was kind enough to tell
me that the SATA/PATA drivers were not on by default, and I got past that problem.

As a second attempt (well 3rd or 4th) I have done a normal config, trying to
delete as many things as possible to speed up the compile time.

I have now got by the dreaded /dev/root error I had with no drivers, but have
a new problem. The boot looks like this (typed from my notes, so probably
not exact)

Take the "quiet" option off the kernel command line (in /etc/grub.conf) so you can actually see all the messages that are being output. Presumably you haven't selected something that you need in order to mount the root filesystem..
