Yes it's the good way to load the modules, but the problem comes from
scsi_mod with KMOD enable in the kernel, that scsi_mod whant modprobe
scsi_hostadapter when no adpater is released ... and the error appear
when do_exec counldn't exec /sbin/modprobe in current fs (ram0) for
strange things :(
I also integrated a little patch in futher kernel release (11mdk) to fix
that (workaround too): no need to load scsi_hostadapter when no adapater
found ... module depenence resolve this :)

scsi_mod : is the scsi middleware interface
sd_mod : try to find scsi_disk via host bus and have implementation of
scsi_disk command
