The problem isn't the amount of CPU usage -- there's more than enough
processor power to go around -- it's poorly-written modem drivers that don't
share the CPU properly. This kind of thing is the source of endless
problems (e.g., modem CRC errors caused by poorly-written video drivers),
which I why I don't allow them on my systems except for testing purposes.

I respectfully disagree. This isn't rocket science, and properly-written
alternatives are readily available.
