Hi all,
I did more restructuring on the patches.
The new isigen plugin is modeled after atgen.
The "isimodem" modem driver is removed.
The n900 modem driver seems to run on Nokia N900 with meego kernel and
userspace.
All the naughty bits that Rémi complained about are now moved into
uspnmodem (and modemconf).
If the modem has (non-zero) integer property "Address", the isigen or
n900 modem driver will configure the interface with the given address.
If there is no "Address", then the modem drivers assume that configation
is done for them.

New subject: [n900-v5 1/5] isigen: generic modem driver plugin for isimodems
From: Pekka Pessi <ppessi(a)hamsa.research.nokia.com>
The new isigen modem driver plugin replaces the generic isimodem modem
driver.

New subject: [n900-v5 3/5] n900: modem driver plugin for Nokia N900
From: Pekka Pessi <ppessi(a)hamsa.research.nokia.com>
The n900 plugin has a modem driver for the N900 internal modem based on
isimodem. It controls the modem using the appropriate GPIO lines.
The plugin can run natively on N900 with Maemo or Meego kernel. However,
it conflicts with the Maemo userspace. On N900 with Maemo, use
modems.conf to set up a isigen driver for phonet0.

New subject: [n900-v5 5/5] usbpnmodem: plug in either n900 or isigen
From: Pekka Pessi <Pekka.Pessi(a)nokia.com>
The usbpnmodem is a stop gap solution until we get udev to support
isimodems. Currently it does the basic configuration of the phonet
interface.
