I didn't look at the script so it may be useful, but it doesn't seem needed
to me when it comes to loading additional modules. To load additional
drivers automatically in Linux 2.6 I use the /etc/modprobe.conf file of the
module-init-tools package. You'll have to create a rule for each and every
driver, but that also gives you the flexibility to create customised rules
on a per driver basis.

examples: (see man modprobe.conf)
install atkbd /sbin/modprobe --ignore-install atkbd && { /sbin/modprobe
i8042; }

install psmouse /sbin/modprobe --ignore-install psmouse && { /sbin/modprobe
i8042; /sbin/modprobe mousedev; }

install hid /sbin/modprobe --ignore-install hid && { /sbin/modprobe
mousedev; }

install hpt366 /sbin/modprobe --ignore-install hpt366 && { /sbin/modprobe
ide-cd; /sbin/modprobe ide-disk; }

install pdc202xx_new /sbin/modprobe --ignore-install pdc202xx_new &&
{ /sbin/modprobe ide-cd; /sbin/modprobe ide-disk; }

install pdc202xx_old /sbin/modprobe --ignore-install pdc202xx_old &&
{ /sbin/modprobe ide-cd; /sbin/modprobe ide-disk; }

install piix /sbin/modprobe --ignore-install piix && { /sbin/modprobe
ide-cd; /sbin/modprobe ide-disk; }

install via82cxxx /sbin/modprobe --ignore-install via82cxxx &&
{ /sbin/modprobe ide-cd; /sbin/modprobe ide-disk; }

options aha152x io=0x0140 irq\x11
install aha152x /sbin/modprobe --ignore-install aha152x && { /sbin/modprobe
sd_mod; /sbin/modprobe sr_mod; }

I hope the above can help you create a customised rule for your device.

I think this also counts for the input.rc script. AFAIK input.rc always runs
before the other .rc scripts. So drivers for input devices will always be
loaded after input.rc has run. Therefore it seems to me that input.rc never
really does anything, unless I'm overlooking something.

I guess that running the hotplug rc scripts in alphabetical order will never
be the right thing to do, unless they get sequenced somehow.
e.g.: Maybe by adding some sequence number like udev-rules and
udev-permissions.
