In terms of modprobe, I have it installed, however Compulab has
included libc-2.2.2 in their 2.6.7 image as opposed to libc-2.2.3. 
Since modprobe requires glibc 2.2.3, I get the following error
whenever attempting to use modprobe:

"modprobe: /lib/libc.so.6: version `GLIBC_2.2.3' not found (required
by modprobe)"

I'm still holding off on reimaging my system with a 2.4.xx kernel as I
will try to obtain or cross compile serial_cs.ko (i just tried to
insmod a serial_cs.o arm binary I found on the web, which didn't work
"insmod: error inserting 'serial_cs.ko': -1 Invalid module format" [I
didn't expect it to work as .o modules are for 2.4.xx only] nor did it
when I renamed the file to serial_cs.ko) first.  So I will need to try
and find the .ko or make a .ko from the source and then attempt to
insmod that.
