The latter patch seems to work:

<snip>
....
puc0: <Exar XR17C/D152> mem 0xfbfffc00-0xfbffffff irq 16 at device 0.0 on pci6
puc0: failed to enable port mapping!

As I already pointed out, I do not have a line connected to the modem yet.
This connection will hopefully be established tomorrow. After some rigorous
testing I will post a mail with the on stream results. On the other hand,
if someone knows some off stream testing procedures, then I'm happy to hear
about that. For the time being I have started minicom and issued:
AT
AT&F
ATI
All with positive and already mentioned results.
