Basically, no. There is no room left in boot0 :(

I think you could do it by squeezing down some text strings, and removing 
other [less common] entries though.

The attached diff is a quick and dirty change which should do it..
I booted my laptop with it so it shouldn't be _that_ broken, but please keep a 
backup :)

to apply..
cd /usr/src/sys/
patch <~/winxp.diff
cd boot/i386/boot0
make
sudo make install
sudo boot0cfg -Bv /dev/xxxx
