BSNL Broadband Connection

I applied for a BSNL Broadband connection, and I called the Junior Telecom Officer for the modem.
JTO : "Do you have Windows or XP?"
Me : (after thinking of what was he asking) Linux.
JTO : "Do you have Windows or XP?"
Me : Linux
JTO : "Do you have Windows or XP?"
Me : Windows XP.

But, what I wanted to say was,

I want to use Asymmetric Digital Subscriber Line Modem with Point to Point Protocol over Ethernet and Dynamic Host Configuration Protocol so that, I can connect to internet from any linux including Hardy Heron, Gutsy Gibbon, Feisty Fawn from Ubuntu, or any variants of Suse, Fedora, Debian, Slackware, and Solaris, without USB modem or any softwares of any platform, and without bothering about hacking by VMWare or Wine. BSNL is the only Internet Service Provider in this area which provides internet like this, and you are expecting me to have Windows. I don't have any software from Microsoft.
