cable broadband and dialup modem

[Robert Holtzman]

Is there any way to have cable broadband and a dialup modem operable on 
the same computer (not operating simultaneously)? The dialup connection 
would be for a separate ISP than the cable connection. Would there be a 
conflict created by adding the dialup ISP's DNS addresses at the end 
of those for the existing cable ISP? What other problems that I'm not 
foreseeing?

I'm trying to figure out a way to use *spit* Cox broadband for browsing 
and downloading linux distros and the dialup ISP for mail and news.
