Just curious, but does your Agere modem have the Mars DSP chip? The PCI
ids for these models would be in the range of 11c1:0440 thru 11c1:045d.
(might also have Xircom vendor id of 115d:) This series has a supported
driver in linux that works with SMP capable kernels, unlike the ltmodem
an ltserial driver. If your modem pci id falls into the range listed
above, and you want try out the "martian" driver with the generic
kernel, you can get it here:

I've used it since feisty and it works well pretty well.
