ddrmat-0.10 on 2.6.6

[Ed Anderson]

Hello,
I assume that the ddrmat module is compiling for everyone else on 2.6.
When I try to compile it,

 make -C /usr/src/linux/ SUBDIRS=$PWD modules

make: Entering directory `/usr/src/linux-2.6.6-rc1'
  CC [M]  /home/nilbus/code/ddrmat-0.10/ddrmat.o
/home/nilbus/code/ddrmat-0.10/ddrmat.c: In function `gc_probe':
/home/nilbus/code/ddrmat-0.10/ddrmat.c:236: warning: implicit declaration 
of function `parport_enumerate'
/home/nilbus/code/ddrmat-0.10/ddrmat.c:236: warning: assignment makes

make: *** [/home/nilbus/code/ddrmat-0.10] Error 2
make: Leaving directory `/usr/src/linux-2.6.6-rc1'

At first I thought maybe I had forgotten to include support for the 
parport module in the kernel, but it is loaded.  
I think my input and hid modules are actually compiled into the kernel, 
not as modules, but I'm not totally sure.  How can I double check?
