You will need a patched kernel to get a few things working right, one of 
them is reboot because the RaQs do not have a standard PC BIOS.  If you 
are interested I have some RH8 kernel RPMS that have been modified to 
add cobalt support.  The binarys are here:

http://cobalt.iceblink.org/redhat/binary/

kernel-cobalt-III-2.4.18-24.8.0.i386.rpm    # for RaQ 3, RaQ 4, Qube 3
kernel-cobalt-V-2.4.18-24.8.0.i386.rpm      # for RaQ XTR, RaQ 550

This kernel includes the LCD driver necessary for the panel-utils 
package to work, but you will need to install the lcd device first:

mknod /dev/lcd c 10 156

There is more information on how these kernels were built as well as the 
required kernel patches available here:
