Linux for low-powered laptop?



Greetings, I have an old Toshiba laptop that I'd like to use as a simple
web access device. It has a Netgear MA521 802.11b wireless card.

Knoppix 5.1 boots fine on the laptop as does Damn Small Linux (a Knoppix
variant), but it's not clear to me how to use the wireless card. I'm
assuming that ndiswrapper will be involved, but using it with a live-cd
distribution is a bit beyond my experience level.

Any help or suggestions would be appreciated.
