FWIW, 5.00 introduced a regression regarding the .psf font loader, 
which was later fixed in 5.10+ (so 5.01 still has this problem).

Considering that 6.03 has so many improvements over 5.xx, IMHO using 
5.xx is not worth the time (unless there is some specific test in 
mind).

These are the reasons for me to suggest the font test in 4.xx and/or 
6.03, skipping altogether the test in 5.xx.
