After upgrading from 7.10 to 8.04 I lost acces to the card. The new rt2500pci driver never worked with my WPA setup. This is kernel 2.6.24-21-generic.
Then I downloaded the from the same link, compiled, installed and blacklisted rt2500pci. After reboot my wireless network worked again with the old settings.
Since I am unsure how stable the tarball is, I will attach the one I used.
I can confirm, that jan's method works.
