I have a K7S5A with onboard LAN. 

I am compiling the driver (SIS900) as module and I have crc32 lib built
in the kernel. When I run "make modules_install" or "modprobe sis900"
afterwards I get 

bear:~# modprobe sis900
/lib/modules/2.5.3-xfs-k7/kernel/drivers/net/sis900.o: unresolved symbol
crc32_be
/lib/modules/2.5.3-xfs-k7/kernel/drivers/net/sis900.o: insmod
/lib/modules/2.5.3-xfs-k7/kernel/drivers/net/sis900.o failed
/lib/modules/2.5.3-xfs-k7/kernel/drivers/net/sis900.o: insmod sis900
failed

Relevant portions of .config:

# CONFIG_8139TOO_TUNE_TWISTER is not set
# CONFIG_8139TOO_8129 is not set
CONFIG_SIS900=m
# CONFIG_EPIC100 is not set
# CONFIG_SUNDANCE is not set

#
# Library routines
#
CONFIG_CRC32=y
CONFIG_ZLIB_INFLATE=m
# CONFIG_ZLIB_DEFLATE is not set
