Hmmm... did you unload the modules from the last test
(i.e.: /sbin/rmmod <module>)? Note that you can use /sbin/insmod <module>
to insert modules, /sbin/rmmod <module> to remove modules, and /sbin/lsmod
to see the currently loaded modules.
It is best to do this by hand as the makefiles seem to be broken for
the examples.

Right, the 1.2 version seems to install the modules in
/lib/modules/2.0.36.RTL1.2/misc - which is consistent with the location
of "normal" linux modules. This breaks the 'make test' part of many of
the examples and is a change from 1.1.

Nope, you're probably ok.

Yep, busted makefiles.

This is typical for Linux installs, for obvious security reasons (you
don't want to pass the root passwd over an unencrypted net). However, you
can telnet in as a regular user and 'su'. (...which then also provides
your passwd unencrypted -- you should probably use ssh in place of telnet
in any case, but it sounds like that's a project for another day. :)

Hang in there. The world is about to become a beautiful place, where
deadlines are always met and every task executes with sub-millisecond
precision.
