What do you mean by "RSA", an RSA key for ssh1 auth or an RSA key
for ssh2 auth? 

Assuming your sshd_config contains

  Protocol 2,1

and your collegue has a ssh1 RSA key, he has to use '-1' on
the CLI.  Otherwise, if sshd_config contains
  Protocol 1,2

you have to use -2 on the CLI.

Another approach is to change your and your collegues ~/.ssh/config
on the client box to do the right thing when connecting to that
server, anyway.

Btw., RSA is assumed to be more secure than DSA.  I suggest using an
ssh2 RSA key, too.
