OK,  On my system (Gentoo 2005.1) there are not /dev/scd* devices (2.6.13
kernel, UDEV enabled),  there are however /dev/sr* (which correspond to the
SCSI cdrom's)

after booting check /dev/ to see if /dev/scd* exists, same wiht /dev/sr*  if
the sr ones exist but not the scd's then just adjust your mount lines in
/etc/rc.d/rc.local.      I though that redhat DID have some init module to
manually load kernel modules (like your AHA1542 module and the cdrom and sr_mod
modules)  I donno what redhat calls it as I dropped that distro years ago after
suffering way too much RPM hell.
