[Yum] downgrade howto?

[mw-list-yum at csi.hu]

Since my FC2-FC3 upgrade disabled my box, I'd like to revert the
changes.

Can I somehow use yum to downgrade by box to FC2?  Is there a
downgrade howto I could read?

In fact, it probably is enough to downgrade all packages depending on
xorg-x11.

Thx,

Mate
