After looking more into the problem (and into several files,
/usr/include/linux/kerneld.h, linux/fs/devices.c) I answers most of
my concerns. I have come up with what appears to be a workable solution.
Comments most welcome...

Existing sd_open() in sd.c....
============================================================
static int sd_open(struct inode * inode, struct file * filp)
{
int target;
target = DEVICE_NR(inode->i_rdev);
if(target >= sd_template.dev_max || !rscsi_disks[target].device)
return -ENXIO; /* No such device */
============================================================
Proposed sd_open()...
============================================================
static int sd_open(struct inode * inode, struct file * filp)
{
int target;
target = DEVICE_NR(inode->i_rdev);
if(target >= sd_template.dev_max)
return -ENXIO; /* No such device */
#ifdef CONFIG_KERNELD
/*
* Load any scsi driver modules if we can't find the disk.
*/
if(!rscsi_disks[target].device)
request_module("scsi_hostadapter");
#endif
if(!rscsi_disks[target].device)
return -ENXIO; /* No such device */
============================================================
