The current 2.4.27 kernel package provides 3 (!!!) different
drivers for this kind of hardware:

   drivers/scsi/ncr53c8xx.o                the old ncr driver
   drivers/scsi/sym53c8xx.o                the old sym driver
   drivers/scsi/sym53c8xx_2/sym53c8xx_2.o  the new sym driver

But the current 2.6.8 kernel package includes just the new
sym53c8xx driver:

   drivers/scsi/sym53c8xx_2/sym53c8xx.ko   the new sym driver

Worst of all: It has been renamed! (The old ncr driver is still
in the kernel sources, but it is not built for the kernel
package.)

There are 2 special cases:
a) minor upgrade (i.e. 2.4.x --> 2.4.y, or 2.6.x --> 2.6.y)
	I would agree to Joshua's suggestion to kick the sed
	line out. mkinitrd should rely upon the SCSI driver it
	has found in the running kernel.

b) major upgrade (i.e. 2.4.x --> 2.6.y)
	For this case we need a new sed statement, replacing
	the 'ncr53c8xx' and 'sym53c8xx_2' by the new 'sym53c8xx'.

It seems that the 3rd case (major downgrade) is not supported
by mkinitrd,

Attached you can find a patch for initrd-tools 0.1.74. I know it
is an ugly patch, but it is still easy to extend. Maybe somebody
has another idea how to handle renamed modules?
