Broadcom BCM4311 on OpenSuse 11.2: suddenly Wireless broke

http://forums.opensuse.org – Hello there, I'm happily using OpenSuse 11.2/KDE on my laptop equipped with a Broadcom BCM4311 WLAN chip, but today, after a restart, WLAN ceased to work. I mean that Network Connection doesn't show anymore available WLANs. Two things that seem strange to me are that the Code: lsmod | grep b43 command gives no result and the modprobe gives: Code: modprobe  b43 WARNING: Error inserting pcmcia (/lib/modules/2.6.31.5-0.1-desktop/kernel/drivers/pcmcia/pcmcia.ko): Unknown symbol in module, or unknown parameter (see dmesg) WARNING: Error inserting ssb (/lib/modules/2.6.31.5-0.1-desktop/updates/drivers/ssb/ssb.ko): Unknown symbol in module, or unknown parameter (see dmesg) FATAL: Error inserting b43 (/lib/modules/2.6.31.5-0.1-desktop/updates/drivers/net/wireless/b43/b43.ko): Unknown symbol in module, or unknown parameter (see dmesg) At first I verified that under Windows XP, on the same computer, WLAN works normally as usual (so, I would exclude chip failure). Then, I forced an update (to the same current version) with YAST2 of - compat-wireless-kmp-desktop - b43-fwcutter I also relaunched the /usr/sbin/install_bcm43xx_firmware command. Is there something else I could do?
