Do you have a setup CD? If so, you might be able to fix things with the
recovery console. If not, download the recovery console setup disks from
microsoft's site and run them.

Absolutely. It's pretty easy too. All you have to do is:
1.) Leave the WXP boot sector alone during FreeBSD install so the NT loader
still works.
2.) Copy /boot/boot1 from your FreeBSD setup CD, hard disk, or fixit
media to an msdos floppy disk:
mount -t msdos /floppy
cp /boot/boot1 /floppy
umount /floppy
3.) Boot into WXP, copy 'boot1' from the floppy to your C:\ drive and
call it 'bootsect.bsd', then add an entry in your C:\boot.ini like
this:
C:\bootsect.bsd="FreeBSD 5.1-RELEASE"
Reboot and enjoy.
It's not really quite that cut-and-dry in practice (sometimes you'll have
to manually set the WXP partition as bootable from FreeBSD's fdisk utility,
for example. And when doing a fresh install, you'll probably have to get
boot1 from the fixit media.), but those are the basic steps, and if you
can muddle through them you'll be alright.
