Hello Mike,
There are certainly key loggers available for linux. Here is one example:
http://sourceforge.net/projects/lkl/
Of course, if an attacker is at the point where he or she could load
software like this onto your machine and have access to the
appropriate key-map, then you're probably rooted anyway. I wouldn't
expect this to be a very likely attack method. If somebody is after
your passwords (on a home machine, anyway), then cross-site scripting
is much more common (plus it's effective for multiple platforms).
I hope that helps!
