Я тебя рассторю - у тебя тоже ndiswrapper:
driver=ndiswrapper+bcmwl5

Драйвер для Dell 1395 Mini-board/Broadcom 4310 ещё допиливают:

BCM4310 is a known card, it's an LP-PHY. AFAIK it's still being
reverse-engineered. CCing Larry, he is working on it AFAIK...
...At the moment, b43 does not support the LP-PHY, which we think is a low-power b/g device. The RE team is working hard on the routines found in driver 4.150.10.5, which supports LP and N-PHYs.

>Я тебя рассторю - у тебя тоже ndiswrapper:

А сразу спросить не мог? :) И с чего я должен расстраиваться? ;) Работает и ладно. Фанатизмом не страдаю.

virun - покажи вывод команды:
$ sudo lshw -C network
У тебя вроде без ndiswrapper работает?

> driver=wl

Это чтото проприетарное, но не относящееся к ndiswrapper'у.

Действительно, начиная с версии ядра 2.6.24-18 в ubuntu hardy поставляется Broadcom'овский проприетарный модуль wl, который поддерживает BCM4315.
Нужно установить пакет linux-restricted-modules-2.6.24-18-generic
