I don't think that would be _that_ hard to fix at least for that specific
driver, but I'm not 100% sure.

Have you seen these drivers ->
http://www.smlink.com/main/index1.php?ln=en&main_id=32
It seems to support a lot of software modems, ie
HAMR5600 based AMR/CNR/MDC/ACR modem cards on the following Southbridge
chips:
- Intel ICH0, ICH2
- Via 686A, 686B, 8231, 8233
- SiS 630
- ALI 1535.
SmartPCI56, SmartPCI561, SmartPCI563 based PCI modem cards.
SmartUSB56 based USB modem.
And the binary code appears to only call shim routines for which the source is
available.
