Yes, there is extensive support for the IBM PowerPC 405 embedded processor
family (405 based processors from IBM include the 405GP, 405CR, STB03xxx, NPe405)
available from MontaVista.  The development web site is currently slightly stale:

There is newer source on the ftp site than the web page describes (September 9)
and there should be a newer version of source and an updated web page within
the next few weeks.
