That's a distinct possibility, an IRQ conflict will almost certainly
cause trouble, as would an incorrect IRQ assignment (although I don't
think that's the case here). I don't have laptop experience and so
can't comment on how "card services" on one would led you to believe
the IRQ is involved.
If you haven't already, to be sure there is an IRQ conflict, do
cat /proc/interrupts
to see if something else uses the IRQ used by the modem's serial device.

You might think of it as gathering Karma. :) But, yes, there can be
problems with upgrading and they are at times annoying.

Debian is highly regarded by a friend of mine, who has his own computer
farm (many networked computers), and seems to have very few problems
updating with those package upgrade programs. I use Slackware and as
a result have a fairly high Karma - but it's been worth it to me; I've
learned a lot.
Note that technically this is not a pppd problem, but rather a problem
with modem, or serial device configuration, or the modem driver.

The best answer I can give to "how IO is assigned" is manually or, for
PCI, automatically and perhaps according to the order the cards are put
in the MB slots. Manually can mean using setserial, or reordering the
cards, or, in some cases, it might mean configuring the BIOS to reserve
an interrupt and then using setserial.
As to never learning "why," are things really any different for other
operating systems? Especially closed source OSs - unless you pay for
support and even then I'm not sure how detailed the reply to a "why"
question would be.
If it turns out not to be caused by an IRQ configuration then you might
try replacing the "AT OK" in the chat script with "ATZ OK" that your
first post said minicom used on a successful dial out. Or AT&F might
be even better, if it works at all. I'd also check the serial device
setting of minicom.
