RFC 4432 (formerly draft-harris-ssh-rsa-kex) defines a means to use RSA key exchange in SSH-2 (similar to SSH-1's key exchange, but without the other disadvantages of SSH-1). This might be particularly suitable for slow client systems.

SGT, 2012-06-22: Perhaps this is as good a place as any to keep a list of known server-side implementations.

OpenSSH bug #1314 includes a patch which adds RSA key exchange to OpenSSH, although the OpenSSH maintainers decided not to integrate it in the end.
MouSSH supports RSA key exchange. (It looks as if the FTP link here is the most convenient way to get MouSSH: you'll need the contents of that directory and several libraries in directories alongside it – see the INSTALL file for a list – and I haven't personally confirmed that it compiles and works.)
The mod_sftp module for ProFTPD is documented as supporting RSA key exchange. (But it looks as if you can't do anything except SFTP over the resulting connection.)
