USB modem working on RH but not Slackware

I have a USB modem that I know is linux compatible as I had it working on RH9 with kudzu.

Now that I switched to Slackware 10 I don't seem able to make it work.

I compiled my own kernel 2.6.9 with USB phone module and CONFIG_HOTPLUG=y
As far as I can tell I also have udev installed and this is what swaret reports:
Listing available Packages matching Keyword: udev...
udev-050-i486-1 (169 kB) [Status: NOT INSTALLED (Installed: udev-042-i486-1)]

When I plug the modem in, lsmod shows that the cdc_acm module gets loaded but the module does not seem to bind to the modem.
This is what I see in /proc/bus/usb/devices

T: Bus=01 Lev=00 Prnt=00 Port=00 Cnt=00 Dev#= 1 Spd=12 MxCh= 2

E: Ad=81(I) Atr=02(Bulk) MxPS= 16 Ivl=0ms
E: Ad=01(O) Atr=02(Bulk) MxPS= 16 Ivl=0ms
I: If#= 0 Alt= 0 #EPs= 1 Cls=02(comm.) Sub=02 Prot=01 Driver=(none)
E: Ad=82(I) Atr=03(Int.) MxPS= 8 Ivl=128ms

I also don't seem any ACM nodes in my /dev directory but I guess that is to be expected with udev.

I am a bit confused with the udev/devfs and I am not sure if I have either of them configured correctly.

What really gets me is that the module doesn't seem to recognise the modem. What am I doing wrong?
