My problems are solved so far. Here is a mail exchange in case anyone has similar problems.

Hi Stefan,

sorry for the delay, your advice with "purge" was the solution, and I did it right away.(apt-get remove --purge dkms)

However, before writing an answer to you and a comment to the bug report, I had to see that the wireless worked as well.

It didn't.

In the past (1-2 months ago) I had the problem that, even though I did everything as indicated on the official broadcom site to download and install the 802.11 Linux STA driver, at boot it would always load the wrong modules. With help from <email address hidden> I was able to change the boot image (with "update-initramfs -u") and it booted correctly ever since - until this version 2.6.31.19.32

Now since I had this bug signalled, I tried to repeat the exact same steps, but changing the boot image did not work anymore (I could do it, but at reboot nothing changed). I suppose it had to do with the bug, smth with meddling with the image, but I don't understand enough to follow the exact problem.

So the solution now was that I had to make my own script to be run at boot time. Now everything works, but I am concerned as to why the script was necessary at all.

The script consists of just these two lines:

sudo modprobe lib80211
sudo insmod /lib/modules/2.6.31-19-generic/kernel/drivers/net/wireless/wl.ko

Thanks, and maybe this info is helpful to others, so I am posting it on the bug report page as well, as you suggested.

In case apt is not happy yet, you could try to run "dpkg --reconfigure -a", in the hope that this will get the installed packages back in a sane state. Finally you should be able to reinstall dkms which hopefully won't result in an empty file.
