asterisk users - Oct 2004 - Modprobe zaptel fails: Unknown symbol crc_ccitt_table

I'm adding an X100P clone to my Asterisk box, and I'm having trouble
with
the zaptel module. I'm running Gentoo linux with a vanilla 2.6.8.1 kernel
with devfs. I have emerged zapata, zaptel, libpri, and Asterisk (all version
1.0.0.) 

Zaptel compiles (with USE="devfs26") once I've corrected a syntax
error in
/usr/include/linux/ixjuser.h (as per
http://lists.digium.com/pipermail/asterisk-users/2004-August/059263.html .) 

The trouble is, when I modprobe zaptel, I get:- 

server root # modprobe zaptel 
FATAL: Error inserting zaptel (/lib/modules/2.6.8.1/misc/zaptel.ko): Unknown
symbol in module, or unknown parameter (see dmesg) 
dmesg 
<snip> 
zaptel: Unknown symbol crc_ccitt_table 

I've had a look through the Gentoo bugzilla, but I'm not sure if the
combination of zaptel + 2.6 kernel + devfs is supported (yet.) I have asked
a question similar to this on the Gentoo forum, without response.  I guess
it's also possible that my X100P card is not compatible - here's what
lspci
and cat /proc/pci have to say about it:

By coincidence, I upgraded my * box to 2.6.8.1 today.  I encountered the
exact same problem.

Compile a kernel with CONFIG_CRC_CCITT=y and the problem will go away.  Building
it as a module will probably also work.

(this is a kernel glitch; that symbol is being unconditionally included in
the module symbol table)
