For one thing, generic IDE support is certainly less appropriate than
support for your IDE card.  Hardware-specific options cna be enabled
and you might gain DMA if your hardware is really unusual.  I can say
from experience that generic ide support doesn't provide anything that
drivers specific to your hardware fails to provide, unless I
misunderstand greatly. It's not a question of increased functionality
necessarily, but one of performance, and possibly less overhead for the
CPU.  

Secondly, in addition to some kind of driver for IDE, either generic or
specific, you need the cdrom driver (module: cdrom.ko) for cdrom
support.  

My guess is, you upgraded the kernel and fell into the commonly
experienced PATA driver burn -- there's two driver sets now, an
experimental one and the old ones, and you have to make sure to get the
right one for your configuration.  

Dont forget, you'll also need to have the ISO9660 and possibly UDF
filesysem supported.
