Exactly. I found the problem in compat-rdma-3.5/config.mk. As you can 
see below, the build only thinks that it has SP2 if the KERNEL_SUBLEVEL 
is 13, otherwise it thinks it has SP3. I'm working on a fix, but the 
problem is that according to a Novell wiki page I was looking at, SP3 
had an original kernel version of 3.0.76. Hence the valid kernel version 
ranges for SP2 and SP3 overlap.

...
  KLIB_SOURCE := $(subst build,source,$(KLIB_BUILD))
  NAME := $(shell grep ^NAME $(KLIB_SOURCE)/Makefile | sed -n 's/.*= 
*\(.*\)/\1/p')
  ifneq ($(NAME),)
  ifeq ("$(strip $(NAME))","Sneaky Weasel")
  SLES_MAJOR := "11"
  KERNEL_SUBLEVEL := $(shell grep ^SUBLEVEL $(KLIB_SOURCE)/Makefile | 
sed -n 's/.*= *\(.*\)/\1/p')
  ifeq ($(KERNEL_SUBLEVEL),13) <- this is the problem!!
  SLES_MINOR := "2"
  CONFIG_COMPAT_SLES_11_2 := y
  else
  SLES_MINOR := "3"
  CONFIG_COMPAT_SLES_11_3 := y
  endif
