And yes, you assume right. :-)
New edit: I tried kernel 2.6.27-rc3-git6 and it still doesn´t work.

Please attach the output of this command: objdump -d /lib/modules/`uname -r`/kernel/net/wireless/cfg80211.ko The backtrace leaves cfg80211_netdev_notifier_call very early...it could be getting passed something bad as input. What is mcount_call? Seems to be related to ftrace...please also attach your .config file.

Can you disable CONFIG_FTRACE ("Kernel Function Tracer") and rebuild? Can you recreate the problem with ftrace disabled?
I'm sry that it took some time with my answer. I'm not so firm in building a kernel. I tried it as you requested with a disabled CONFIG_FTRACE and there was no change. But maybe that information will help. I tried ubuntu 8.10 beta and with the livecd i can boot up and have a connection with this USB-WLAN-device.
AFAICT, mcount_call (which is in the trace you provided) doesn't exist if CONFIG_FTRACE isn't set...are you sure you are running a build with CONFIG_FTRACE turned-off? If so, then the trace should have at least that difference (i.e. no mcount_call)?
I would like you to do two things: Attach /etc/udev/rules.d/70-persistent-net.rules to this bug; and, delete /etc/udev/rules.d/70-persistent-net.rules and reboot. Does the problem persist after the 2nd part above?

I've found a small bug that might have been causing this, see http://thread.gmane.org/gmane.linux.kernel.wireless.general/21902
