# The following build rules were defined as such in order to properly support
# initial versions of the 2.6 kernel where the kbuild environment had not yet
# stabilized (i.e. Suse 9.1, 2.6.4-52). The two changes which needed to be made
# were:
#    
#    1. The make command defines the SUBDIRS variable to be the location of the
#       module code, instead of using the newer M variable. In Suse 9.1, using
#       M would for some reason cause a rebuild the entire modules tree without
#       building our module.
#   
#    2. A seperate 'clean' rule had to be defined which manually cleans our
#       module directory. On newer 2.6 kernels, calling into the kernel dir's
#       Makefile would clean our module directory properly, but this doesn't
#       happen in older kernels (again, Suse 9.1, 2.6.4-52).
