You were on the right track with the emergency shell, but the "Fixit" mode 
(now included on disk 1 for your convenience) gives you a lot more 
flexibility (inclusion of "ls" is just the start!). Have you tried something 
like this?

1) Boot to complete install CD
2) Go into "Fixit" mode (not just the emergency shell)
3) # sysctl kern.module_path="/dist/boot/kernel"
4) # kldload twa
5) # exit
6) proceed with installation

This shouldn't be necessary though, since twa is included in GENERIC for both 
FreeBSD 6.1 and 6.2 (did you say what version you were trying to install?).

Now, if your controller is too new to be included in the shipping version of 
twa then that's another matter. If you have a binary kernel module that uses 
a different driver name from the vendor you could use the same general 
approach, but you'd want to configure your network interface and set up your 
NFS mount prior to step 3, and include the appropriate NFS path in the sysctl 
command in step 3.
