The number of texture units and the maximum texture size are not really related in any way. The number of texture units tells you how many textures you can use simultaniously when drawing geometry (how many textures can be bound at once). You can have more textures in video ram than there are texture units, however, you can only bind #texture units textures at any time. A maximum of 2 texture units is sufficient for most scenarios where you have a diffuse texture and a lightmap for example.
The maximum texture size is really just an estimate with most drivers and depends on things such as internal storage (which might be fixed by the driver anyways) and so on. In any case, both numbers will differ from device to device or rather chipset to chipset.
