Do not edit rc.M, just chmod -x rc.hotplug to disable hotplug
Code:
...
if [ -x /etc/rc.d/rc.hotplug -a -r /proc/modules ]; then
...
See ? if rc.hotplug is not executable, it will not be executed
You have to edit rc.modules and add modprobe lines with the correct
modules for your net cards (maybe try modprobe tulip for the built-in one)

Also could you post the output of :
Code:
ls -al /lib/modules/2.4.26

If you want to keep using hotplug & get rid of the warnings, you can add the modules i810_rng and hw_random to /etc/hotplug/blacklist

This way, Hotplug will start but not try to load the kernel modules i810_rng & hw_random

As it is these arent errors, but warnings which inform you that the random number generator & hardware random number generator arent present in your system.

echo i810_rng >> /etc/hotplug/blacklist
echo hw_random >> /etc/hotplug/blacklist

...should append the lines you want in /etc/hotplug/blacklist

you can also use the command line editor called 'pico'.
eg.
pico /etc/hotplug/blacklist
ctrl + o (save)
ctrl + x (exit)

as for the errors, hotplug is good to use, i recommend you keep using it. If you want to get rid of the errors, then do what slaxnoob said above and add them to the black list.

Or if you wan't to do something a bit more difficault, get rid of them from the kernel and recompile.. but blacklist is good enough

i810_rng is only needed if you have an intel i80 chipset on intel motherboards.

hw_random is needed if you are on an intel i9xx based, amd 76x based motherboards, or via nehemiah cpu.

Quote from kernel 2.6.11.5
Quote:
Intel/AMD/VIA HW Random Number Generator support (HW_RANDOM)

This driver provides kernel-side support for the Random Number
Generator hardware found on Intel i8xx-based motherboards,
AMD 76x-based motherboards, and Via Nehemiah CPUs.

Provides a character driver, used to read() entropy data.

To compile this driver as a module, choose M here: the
module will be called hw_random.

If unsure, say N.
To sum it up, i doubt you need them, and since your machine is running now without them, i wouldn't worry too much about it

I have the same issue on 3 computers of mine, and i just blacklisted them.. Everything still works fine.

EDIT:
========
Regarding your usb, if you plug in anything, and type
dmesg
does it show anything? or that it tried to detect it?
