8x8 is a bit big for the smaller displays, and it also takes up more flash than a smaller font.

I did actually start on a 3x5. You can have some fun with the preprocessor to allow you to pack everything in quite nicely:

#define ___ 0
#define __X 1
#define _X_ 2
#define _XX 3
#define X__ 4
#define X_X 5
#define XX_ 6
#define XXX 7
#define PACK_5_TO_16(A,B,C,D,E) ((A) | (B<<3) | (C<<6) | (D<<9) | (E<<12))
 // 48

const unsigned short LCDFONT_3_5[10] = {

    PACK_5_TO_16( XXX , _X_ , XXX , XX_ , X_X ), // 01234
    PACK_5_TO_16( X_X , XX_ , __X , __X , X_X ),
    PACK_5_TO_16( X_X , _X_ , _X_ , XX_ , XXX ),
    PACK_5_TO_16( X_X , _X_ , X__ , __X , __X ),
    PACK_5_TO_16( XXX , XXX , XXX , XX_ , __X ),
                      ,     ,     ,     ,
    PACK_5_TO_16( XXX , XXX , XXX , XXX , XXX ), // 56789
    PACK_5_TO_16( X__ , X__ , __X , X_X , X_X ),
    PACK_5_TO_16( XXX , XXX , _X_ , XXX , XXX ),
    PACK_5_TO_16( __X , X_X , _X_ , X_X , __X ),
    PACK_5_TO_16( XXX , XXX , _X_ , XXX , XXX )

};

Potentially a variable width font would make more sense if we're going for 5 pixels high though.

Fixed. Used 4x6 - still almost 1/2 the ROM and it looks better.
