This will break because of the contents of the /etc/fstab.

This was to clean up the additions for IDE-devices.

This is the second case that I know about where the on-board ide-chipset
is given a higher pci-bus number than the pci-slots.
The ASUS P55T2P4D (Intel 430HX), some 486 (UMC UM8881F), and maybe other
mainboards may do this oddity. This blows the plan for using the
addition to the lilo.conf append line of "pci=reverse".

I wanted to avoid hard-setting of bootablity of add-on cards to have
some flexablity. The goal was to prevent the silly game of card/slot
order (I recall some discusion about this with SCSI crowd).

The second option that just came to mind is to allow one to only reverse
the IDE-controller scan order. This would allow "pci=reverse" to still be
called with the constraints of imposed by my first patch against my
changes added into 2.1.122. This sounds better and retains to orginal
flexablity.

Not need, unless there is something that I truly missed.

Sometime late tonight or in the morning will post a second method
against pci-bus-number-order for IDE controllers.

The first was "pci_ide_order-2.1.122.patch"
