Compiling Linux modem drivers on FreeBSD?

[aydun]

Hi,

I've ended up with a SmartLink PCI softmodem (SmartPCI561).  SmartLink
provide some drivers for Linux which apparently are quite good at
ftp://ftp.smlink.com/linux/unsupported/

This comes as some source code and some object files with needs to
compiled against a kernel source tree - which looks simple enough on Linux.

I have the linux_base port installed on FreeBSD 4.9.  I don't have a
Linux kernel source tree, but is it just a matter of compiling against 
the Linux kernel source and linking the Linux libraries?

Even assuming it does compile, what are the chances of it actually working?

And yes, I know its quicker and easier to buy something else, and lots
of people don't like softmodems etc etc.  That's not the point :-)  Can 
it work??

thanks
