I'm sort of stuck where you are...

anyone to toss a bone here on compiling kernel modules

I'm following the release notes:
Note
An exploded source tree is not required to build kernel modules against
the currently in-use kernel.

For example, to build the foo.ko module, create the following file
(named Makefile) in the directory containing the foo.c file:


obj-m    := foo.o

KDIR    := /lib/modules/$(shell uname -r)/build
PWD    := $(shell pwd)

default:
    $(MAKE) -C $(KDIR) SUBDIRS=$(PWD) modules

so 
# ls -l
total 204
-rw-r--r--  1 root root    137 Aug 13 23:36 Makefile
-rw-r--r--  1 root root    140 Aug 13 23:33 Makefile~
-rw-r--r--  1 root root 118447 Jun 24 12:42 megaraid.c
-rw-r--r--  1 root root  29506 Jun 24 12:42 megaraid.h
-rw-r--r--  1 root root   2808 Jun 24 13:04 scsi.h
-rw-r--r--  1 root root   4146 Jun 24 13:05 scsi_obsolete.h
-rw-r--r--  1 root root    215 Jun 24 13:05 scsi_typedefs.h

# cat Makefile
obj-m   := megaraid.o

KDIR    := /lib/modules/2.6.9-11.ELsmp/build
PWD     := $(shell pwd)

default:
        $(MAKE) -C $(KDIR) SUBDIRS=$(PWD) modules

then running the following...I'm shooting blanks...

# make -w
make: Entering directory `/usr/src/megaraid'
make -C /lib/modules/2.6.9-11.ELsmp/build SUBDIRS=/usr/src/megaraid modules
make[1]: Entering directory `/lib/modules/2.6.9-11.ELsmp/build'
make[1]: *** No rule to make target `modules'.  Stop.
make[1]: Leaving directory `/lib/modules/2.6.9-11.ELsmp/build'
make: *** [default] Error 2
make: Leaving directory `/usr/src/megaraid'

Anyone care to toss a bone my way?
