I tried this, and the installation went through fine. But after 
installing 3.2, I get a `Missing operating system' when I try to
boot the second partition (the first still has its type set to 
something other than FreeBSD, so it won't boot either).

Robert, you seem quite knowledgeable about all this, and seem to have
had considerable success. How do I get this right? I want to install
2.2.8 in one partition and 3.2 in another. If I don't change the 
fdisk partition type after installing 2.2.8, then sysinstall won't
allow me to install the second OS (it complains when I try to make the 
root BSD partition that the boot loader can't handle it). If I do
change the fdisk partition type first, the install is fine, but I can't
boot afterwards, as described above.
