Or this?
cat /proc/bus/pci/devices
Lots of useless 00000000 data, but card identifiers can be found
there... e.g. on my laptop, the last thing that shows up is my pcmcia
ethernet card, which is identified as 3c59x ... which is
the same name as the module I load to get it running.
The "failed to start interface" line sounds to me like your
new kernel build or modules installation didn't include support
for your card.
There might be more informative messages somewhere in /var/log.
A good general tactic when something fails is to do ls -lrt /var/log/*
... that will show you the most recently changed logfile(s), and
if you do a tail on that file, you may find more detailed
error messages which can, at the very least, give you more ammo for
google groups searching.
Anyway, assuming it is indeed lack of a loadable module:
see if there's an appropriately named module somewhere under
the /lib/modules/new_kernel_version_number/ heirarchy.
maybe it didn't get loaded.
Try to load it, then try your dialer program again.
If nothing looks like the right module, go back to /usr/src/linux,
run "make xconfig" again, and look for appropriate modules for
your card. For my pcmcia modem, IIRC all I had to do was go
into Character Devices, choose PCMCIA Character Devices (near
the bottom), and say Y to PCMCIA serial device support.
I didn't say M because, for crucial things like net access,
I prefer to ensure that it always works without having to
load modules. Like when booting from an emergency floppy where
there's no room for modutils. (I do the same thing with
most filesystem support.)
But if you prefer, you can build it as a module.
Just be sure you do
make modules
make modules_install
...after building the new kernel.
