Bug#290644: debian-installer: can load wrong IDE driver when root filesystem is not on this controller

[Robert Kroiss <rkroiss@iwag.tuwien.ac.at>]

Package: debian-installer
Severity: normal

On a freshly installed sarge system there are two lines in the
/etc/modules:
ide_generic
ide_cd

If the root filesystem is not on the same controller as the cdrom/dvd
drive this loads the generic IDE driver for the controller where the
cd/dvd drive is installed. This driver has no ability to use DMA/UDMA
on most controllers and thus results in inferior performance of the 
cdrom/dvd drive.

This bug does not affect systems with the root filesystem on the same
controller as in this case the correct driver is loaded during boot
(initrd) before /etc/modules is being considered.

Suggested fix:
Insert the driver for the detected IDE controller into /etc/modules
before the other two entries or at least warn the user about the
possible problem.

Best regards,
Robert Kroiss
