Your kernel configuration for IDE seems to be wrong. You're using 
ide_generic which no remotely modern system should be using. You should 
enable one of the chipset-specific drivers under "PCI IDE chipsets 
support". I suspect there was a change so that ide_generic no longer 
attaches to your IDE controller whereas it did before.

(Really if you're up for making changes one should just disable the old 
IDE stuff and switch to libata but that's another matter.)
