Here is what I have been able to find:

Porsche
five-speed transaxle or five-speed Tiptronic S dual-function transmission

Gear Ratios (manual)
1st 3.50:1
2nd 2.12:1
3rd 1.43:1
4th 1.03:1
5th 0.79:1
Reverse 3.44:1
Final Drive 3.89:1

Gear Ratios (Tiptronic S)
1st 3.66:1
2nd 2.00:1
3rd 1.41:1
4th 1.00:1
5th 0.74:1
Reverse 4.10:1

ETKA, but it takes a while, even for one specific tranny code - here are just the basic engine/tranny combos for 1999-2000 Passat 4-cylinder TDIs w/ manual trans (MKB = Motor Code, GKB = Tranny Code):

For example, the ELN / ELP transmission (6 speed) lists as:

Final drive: 3.875
1st - 3.50
2nd - 1.889
3rd - 1.231
4th - 0.871
5th - 0.667
6th - 0.561

The five speed EXC / EYZ list as:

Final drive: 3.625
1st - 3.50
2nd - 1.889
3rd - 1.231
4th - 0.871
5th - 0.667

As AUDI lists them:

Trans Type: 5
1st - 3.50
2nd - 1.889
3rd - 1.231
4th - 0.871
5th - 0.667
