Great.
One last detail. When /opt/.alsadriver exists, I will let the module specified in it be modprobed without depending on an ISA card first being detected, to give user control in the event an existing ISA card is not detected by the script first. Automatic modprobing of known ISA modules will of course remain contingent on hardware first being detected and the lack of a successful modprobe/setup of an /opt/.alsadriver entry. If there is one or more entry in /opt/.alsadriver, and an ISA sound card is detected in the system, and it dos not result in the card being activated, the script will then resort to the automatic modprobing. That should be the last changes unless bugs are found.
