Comment 5 for bug 213639

So take amd74xx.ko module from linux-image-2.6.24-12 package, put it into /lib/modules/2.6.24-16-generic/kernel/drivers/ide/pci/ and add "blacklist pata_amd" to /etc/modprobe.d/blacklist file. Reboot and you'll have old config - working one! :)

PS. If you don't find linux-image-2.6.24-12 package (latest is linux-image-2.6.24-16 and all older seem to be removed from all archives in preparation for Hardy release) I can put it here (whole or only IDE modules).
