Well, it can't hurt to try it and I have found the results to be quite satisfactory. BTW, these are the fonts I am using for Mozilla under Knoppix:

Proportional: Sans Serif /16 px
Serif: Tahoma
Sans Serif: Veranda
Cursive: Comic Sans MS
Fantasy: Serif
Monospace: Andale Mono /15 px
Minimum Font Size: 15 px
Screen: 1024x768

Looks pretty darned good.
