which one I can safely removed to lose some weight?

[lina]

Hi,

after install the b43 related packages, my / become so heavy suddenly, 
reached 84%.

now

:/lib/modules/3.2.0-1-lina/updates/drivers/net/wireless# ls
adm8211.ko       brcm80211     libertas           orinoco        rtlwifi
at76c50x-usb.ko  ipw2x00       libertas_tf        p54            wl1251
ath              iwlegacy      mac80211_hwsim.ko  rndis_wlan.ko  wl12xx
b43              iwlwifi       mwifiex            rt2x00         zd1211rw
b43legacy        iwmc3200wifi  mwl8k.ko           rtl818x

root@dove:/lib/modules/3.2.0-1-lina/updates/drivers/net/wireless# du -sh
141M    .

I wonder above director, which one I can safely remove:

# lspci | grep Broad
02:00.0 Ethernet controller: Broadcom Corporation NetXtreme BCM57765 
Gigabit Ethernet PCIe (rev 10)
02:00.1 SD Host controller: Broadcom Corporation NetXtreme BCM57765 
Memory Card Reader (rev 10)
03:00.0 Network controller: Broadcom Corporation BCM4331 802.11a/b/g/n 
(rev 02)


I can keep it, just in case there are some redundant packages to take 
the place,

Thanks for any advice,

I assume you are talking about some embedded system.  Remove the modules
under drivers/ except those that are used during normal operation. The
list of loaded modules is in /proc/modules.

I can imagine that some modules may or may not be used dependent on
the mode of operation (e.g. whether encryption is used), but they are
not under drivers/
