Put the two directories on /dev/sdb1 and than make symbolic links in
your / directory.
E.g:

mount /dev/sdb1 /vol
ln -s /vol/home /home
ln -s /vol/var /var

If you use two partitions on /dev/sdb you have the problem to choose
the size for /home and /var separately and it is tough to change when you 
find out that e.g. /var on /dev/sdb1 needs more space and /home on
/dev/sdb2 has 200MB free. 

I had to do the same thing. I moved my /home and my /usr/local
directories on a differnt partition because they were getting too
large for the boot partition. I all works fine now.
