** Description changed:
I'm using Hardy Heron.
My laptop has two interfaces, wired (eth0) and wireless (eth1).
When trying to reach the address 169.254.0.1 on my network, I fail (no
route to host from 169.254.9.20).
I expected to recieve a reply from 169.254.0.1.
When I disabled eth0 (sudo ifconfig down eth0) it started to work.
So, for some reason, eth0 (which was disconnected) was interfering with
the routing.
Here's some extra info:

+ EDIT:
+ It seems to me that this might be related to the fact that I got vmware
installed, that a bridged interface is messing things up for me. Can some one
confirm that bridged interfaces interfere with the routing of 169.* addresses?
