Actually no.  /proc/scsi is

 (a) not present on all 2.6 kernels (only if "legacy /proc/scsi/ support"
     is enabled)
 (b) even if it is enabled on mainline kernels only drivers who actually
    have a ->proc_info method show up there.  Debian kernels have a
    totally broken patch that Herbert added to make mkinitrd still work.

So mkinitrd simply must not rely on /proc/scsi at all when running on
2.6 kernels.
