I cannot reproduce your problem using my 4311. I downloaded a fresh copy of 
2.6.21 and patched it 
with the combined-2.6.21.patch from my FTP site. When I rebooted it came up 
just fine. In addition, 
I never see the kernel panics when removing the module. I use NetworkManager, 
which prevents an 
ifdown command, thus I just issue a 'modprobe -r bcm43xx' command. When you get 
a panic rather than 
a frozen system, please post the kernel panic dump.

I have sometimes seen a problem when switching between bcm43xx-mac80211 and 
bcm43xx-softmac. The 
symptoms are 'bcm43xx: IRQ_READY timeout' and 'bcm43xx: core_up for active 
802.11 core failed (-19)' 
messages, which indicate that the firmware is not running correctly. Sometimes 
unloading and 
reloading the module will fix this, but it may require powering the system off 
(cold reboot).

The standalone version does not have the recent patch that properly sets the 
channel range based on 
the locale setting. Thanks for noting this.
