Jeremy,
I'm no expert, but got a USR 5610A internal modem working under potato
(kernel 2.2.19pre17) by slightly modifying the instructions posted at
http://www.math.sunysb.edu/~comech/tools/PCImodems.html (going down at the
end of this month, BTW). Don't know why woody would be different. I've
attached the relevant part below. Step IV is different in Debian--I'll get
back to you when I check my Debian installation.
Hope this helps,

***INSTALLATION OF V90 PCI LUCENT VENUS BASED MODEM***
I. After physically installing the modem, log into your "Root" account.
II. To determine resource settings.
Type the following command: cat /proc/pci
An example of the outcome will look like this;
5. Non-prefetchable 32 bit memory at 0x00000000.
Bus 0, device 17, function 0:
Communication controller: Unknown vendor Unknown device (rev 0).
Vendor id=11c1. Device id=480.
Medium devsel. Fast back-to-back capable. IRQ 11. Master
Capable.
No bursts.
Min Gnt=252.Max Lat=14
Non-prefetchable 32 bit memory at 0xe4000000.
I/O at 0x6400.
I/O at 0x6800.
I/O at 0x6c00.
III. Take note of the IRQ, and FIRST I/O address, then type in this command;
cd /dev; test -c ttyS3 || ./MAKEDEV ttyS3; chmod 666 /dev/ttyS3
setserial /dev/ttyS3 uart 16550A port 0x6400 irq 11
ln -sf /dev/ttyS3 /dev/modem
You can probably use any other ttySX as well.
NOTE: THE IRQ AND PORT MAY VARY, IT IS DEPENDANT UPON THE RESULTS FROM STEP
II
IV. To set Linux to configure the modem upon boot-up.
There are several options. One method is going to the /etc/rc.d/
directory, and using an editing program such as "jed" edit the
rc.local file, and insert
setserial /dev/ttyS3 uart 16550A port 0x6400 irq 11
as the last line.
