You'll probably need to recompile the kernel if mounting the partition doesn't work (I assume you've tried mounting it - otherwise you wouldn't know it doesn't work!).
Under the 'File Systems' section of the kernel config there is mention of 'NTFS (read-only)' or words to that effect. Just select and and your away. There is *experimental* write support I believe but I never played with it.
For info on compiling your kernel have a look at
http://www.linuxdoc.org/HOWTO/Kernel-HOWTO.html if its your first time building the kernel it'll probably seem a little daunting but its pretty straight forward. I won't try to explain anymore as the HOWTO will nodoubt do a much better job.
You might also want to search for Forum for other peoples kernel issues - there are been a few posts recently.
