they had stopped working properly since I upgraded to hardy, so I spent some time to fix both of the problems

for wireless it was easy, because all the firmwares are still in /lib/firmware/2.6.22-14-generic and they weren’t moved to ./2.6.24-12-generic

for graphics driver, fuf, I tried a lot of things and the problem turned out to be that there was a line “blacklist fglrx” in /etc/modprobe.d/blacklist-restricted, commented this line and the driver was enabled automatically right after the reboot.
