Thanks, for coming back to this.
It now gives me a kernel panic after 30 seconds.
I did some debugging using ssleep and printk. b43_fw_cb seems
to be called several times and on the last time the "firmware"
argument seems to be zero. The execution then returns to
b43_do_request_fw, which tries to deference a zero pointer in
the line

It is another machine then last time, has B4306 (rev 3) and a
kernel without modules. The firmware is in /lib/firmware/b43,
which is on the root partition. There is no udev installed.
