Hi Nikolaus

It might be possible to get an account - I have no idea - have you 
tried to ask for one? Or ask for distributors in EU? Samples?:

Broadcom provides access to technical documentation for registered 
customers through our Customer Support Portal. To request an account, 
please contact your Sales/Engineering contacts at Broadcom or its 
Distributors/Manufacturer's representatives directly.

I have no idea if these index pages/refered shops "are for real":

Slow page:
Purchase BCM4329, In-stock BCM4329 From SeekIC.

Last summer, Broadcom suddenly and quietly reversed its anti-Linux 
policies by releasing drivers for certain Broadcom wireless cards. 
Most of the source code is closed, and at this point only a handful 
of chipsets (mostly newer ones) are supported.  But this development, 
which has remained more or less under the radar, nonetheless has 
important implications that extend well beyond the wireless scene.
