That's done by your distribution. I guess it's done with PAM. Check
your distribution's manuals for this keyword.

I'm pretty sure you can change the setup so everytime you login you
/dev/sg1 gets the right permissions.

ls -l /dev/sg1 should show the result. Executable rights doesn't make
sense for device files, as you don't want to run them :-)

man addgroup. But please make sure that you understand what you are
doing. It may not be necessary if you do what I wrote about 1).

That's for the Debian distribution.

Put the options line in /etc/modules.conf instead. And place "modprobe
aha152x" somewhere in the boot scrips, e.g. /etc/init.d/boot.local if
it exists.

No! /etc/modules.conf is not a shell script. man modules.conf.

Put the options line in this file. Now you don't need to give the
options everytime you call modprobe aha152x.
