 Interesting method. I would have tried it, but I got it to work in the
 meantime :)

 This is _nearly_ it - a CONFIG_SCSI_MULTI_LUN kernel is not required,
 but in addition to the options line in modules.conf, one needs to
 rebuild initrd (this is necessary for any SCSI/ATA related changes in
 modules.conf). I found a similar issue in RedHat's knowledge base; the
 command to rebuild initrd on RHEL3u6 is

   new-kernel-pkg --mkinitrd --depmod --install 2.4.21-37.ELhugemem

 And now:
