If you could afford *1* extra HDD (NewEgg, 250 GB EIDE 133 Samsung, 
~$104.00 shipped), you could put /home there, & use the 40 GB as your 
system disk only, with:

/boot   100 MB
/var   10 GB
swap   2 GB
/    the rest

or even

/var   10 GB
swap   2 GB
/   the rest

for a no-virtual-partition (nomenclature ?) solution.

soft-link /tmp to /var/tmp & you're off to the races .... $0.02 only, no 
more, no less :-).
